The 2019 NCAA Division I FBS football season was the 150th season of college football in the United States organized by the National Collegiate Athletic Association (NCAA) at its highest level of competition, the Football Bowl Subdivision (FBS). The regular season began on August 24, 2019, and ended on December 14, 2019. The postseason concluded on January 13, 2020, with the 2020 College Football Playoff National Championship at the Mercedes-Benz Superdome in New Orleans. The LSU Tigers defeated the defending champion Clemson Tigers by a score of 42–25 to claim their first national championship in the College Football Playoff (CFP) era, and fourth overall. It was the sixth season of the College Football Playoff (CFP) system.

November 6, 2019, marked the 150th anniversary of what is traditionally considered the first college football game, played between Princeton and Rutgers in 1869. Various sports media, the NCAA, and the CFP honored the 150th anniversary of the sport throughout the season.^[1][2] Because there were no games played during the 1871 season, this was also the 150th season of college football.

The following playing rule changes have been approved by the NCAA Playing Rules Oversight Panel for 2019:^[3]

• Requiring replay reviews on targeting calls be either confirmed or overturned by reviewing all aspects of the play. If the review cannot confirm that all elements of targeting exist, the targeting call will be overturned. "Stands" is no longer a valid option for replay reviews on targeting fouls.
• Players who commit three or more targeting penalties in the same season will receive a one-game suspension in addition to any ejection penalties.
• Eliminating the two-man wedge on kickoffs, except when the kicking team is in an obvious onside kick formation or if the kick results in a touchback, fair catch, or goes out of bounds in the field of play.
• Starting with the fifth overtime period, each team will line up at the three-yard line to attempt a two point conversion instead of snapping the ball from the 25 yard line. The first game using this new procedure was on October 19, 2019, between the North Carolina Tar Heels and the Virginia Tech Hokies which went to six overtimes before Virginia Tech won 43–41.
• Adding a two-minute break after the second and fourth overtime period.
• Blindside blocks delivered with forcible contact will draw a 15-yard penalty (personal foul). If elements of targeting exist, the player delivering the block will be subject to ejection (and suspension if it's the third targeting foul in the season) as with any other targeting foul.

• January 31 – The NCAA Division I Committee on Infractions banned SEC school Missouri's football, baseball and softball teams from competing in the postseason for the 2019 season and placed the athletics department on 3 years of probation. The penalties were handed down after a 2 year investigation into alleged academic fraud, conducted by the University of Missouri and initiated by former Missouri tutor Yolanda Kumar's allegations in November 2016 that she improperly assisted 42 student-athletes. She claimed she was groomed by her superiors to commit "academic dishonesty" and alleged that she completed online courses and took final exams for Missouri men's basketball and football players. The NCAA Division I Committee on Infractions found that Kumar violated NCAA ethical conduct, academic misconduct and academic extra benefits rules when she completed academic work for 12 student-athletes. The NCAA's report did not find evidence that her colleagues directed her to complete the athletes' work. Kumar was given a 10-year show-cause order, in which any NCAA member attempting to hire her must restrict her from any athletic-related duties. The football, baseball and softball programs will have a 5 percent reduction in scholarships and a 12.5 percent reduction in official visits and evaluation days for the 2019–20 academic year. Further, these sports will face a 7 week ban on unofficial visits, recruiting communications, and off-campus recruiting evaluation days. Finally, the NCAA fined Missouri $5,000, plus 1 percent of each of its budgets in football, baseball and softball. Missouri athletic director Jim Sterk issued a statement saying the school will file an appeal.^[4]
• February 8 – Ohio State Athletic Director Gene Smith announced that he is stepping down from the CFP selection committee in order to focus on helping head coach Ryan Day. He will be replaced by Iowa athletic director Gary Barta.^[5]
• February 12 – Ole Miss Athletic Director Ross Bjork announced that Ole Miss will vacate 33 victories from their football program between the seasons of 2010 and 2016 due to fielding ineligible players. The Rebels will vacate four wins from 2010, two from 2011, seven from 2012, seven from 2013, eight from 2014 and five from 2016, to include a victory over Alabama in 2014. The vacated wins stem from an investigation into the Ole Miss football program involving academic, booster and recruiting misconduct, and a lack of institutional control. Ole Miss had already served a two-year postseason ban in 2017 and 2018 and was given three years of probation, through 2020, as well as scholarship reductions and recruiting restrictions in sanctions handed down more than a year ago.^[6]
• March 9 – U.S. District Judge Claudia Ann Wilken ruled against the NCAA in an antitrust lawsuit, saying football and basketball players should be permitted to receive more compensation from schools but only if the benefits are tied to education. Her ruling said the NCAA cannot "limit compensation or benefits related to education." The claim was originally brought forward by West Virginia football player Shawne Alston, and later merged with other lawsuits, including one brought forward by Clemson player Martin Jenkins.^[7] Judge Wilken had previously ruled against the NCAA in the O'Bannon v. NCAA lawsuit brought against the NCAA by former UCLA player Ed O'Bannon.
• May 13 – The Orange Bowl was rescheduled for December 30, 2019, after initially being scheduled on New Year's Day, 2020. The adjustment was made to allow the 2019 Orange Bowl to maintain its status as a prime-time event. Had it remained on New Year's Day, it would have been scheduled to play in the afternoon, rather than at night. It is not a College Football Playoff Semifinal game this season.^[8]
• June 4 – The Big Ten and SEC announced changes to its bowl tie-ins for the 2020 season through 2025. The two conferences joined the Belk Bowl and Las Vegas Bowl in alternating years; the Big Ten will play the Las Vegas Bowl in odd-numbered years, and the SEC in even-numbered years, both against a Pac-12 opponent. This move acts to heighten the profile of the game, as it plans to move to Allegiant Stadium (future home of the NFL's Oakland Raiders) in 2020. The conference not playing the Las Vegas bowl will play an ACC opponent at the Belk Bowl. The Big Ten will also gain a tie-in for the Florida-based Cheez-It Bowl. In return, the Big Ten will drop the Gator Bowl and Holiday Bowl.^[9][10]
• June 27 – The Big East Conference, following a vote of approval by the presidents of the conference's current members, announced^[11] that the University of Connecticut will be joining the Big East in academic year 2020–21. Thus, the 2019 season will be UConn's last in the American Athletic Conference. UConn had not yet determined which conference their football team will play in, as the AAC will not allow UConn to remain as a football-only member and the Big East does not currently sponsor football. UConn was a charter member of the original Big East when it formed in 1979. The original conference split along football lines in 2013, with three football-sponsoring schools departing for the Atlantic Coast Conference, the seven schools without FBS football leaving to form a new Big East Conference, and the remaining FBS schools joining with several new members to reorganize the original Big East corporate entity as The American. All three members of the current Big East that sponsor football play that sport in FCS conferences.
• July 26 – Multiple media reports indicated that UConn and The American had reached a buyout agreement that cemented July 2020 as UConn's exit date. The fee was reportedly $17 million. UConn also announced that its football team would become an FBS independent.^[12]
• August 19 & 20 – Arkansas State announced that head coach Blake Anderson had taken a leave of absence while his wife Wendy was dealing with a second bout with breast cancer. The following day, the coach posted on Twitter that his wife had died. During Anderson's bereavement leave, Red Wolves defensive coordinator David Duggan served as interim head coach.^[13] Anderson returned to the sidelines for the Red Wolves' September 7 game at UNLV.^[14]
• September 21 – Pitt defeated UCF 35–34 ending the Knights 25-game regular-season winning streak in a game known as the "Pitt Special"
• September 30 – California governor Gavin Newsom signed the Fair Pay to Play Act into law, which upon taking effect in 2023 will prohibit public colleges and universities in the state from punishing their athletes for earning endorsement income. The bill places the state in direct conflict with the NCAA's current rules, which prohibits college athletes from receiving such income. At the time the bill was signed, several other states were proposing similar laws.^[15]
• October 19 – Illinois upset Wisconsin 24–23 on a last-second field goal. The 30 1/2 point underdog's win was the biggest upset in Big Ten football since Northwestern's win over Minnesota in 1982 as a 32 point underdog. This was Illinois's first win over a ranked opponent since defeating Arizona State in 2011.^[16] Also in this game, Wisconsin running back Jonathan Taylor became the 4th player in FBS football history to reach 5,000 career rushing yards during his junior season (including bowl games), joining former Georgia running back Herschel Walker, former Wisconsin running back Ron Dayne, and former Oregon running back LaMichael James. Taylor reached this milestone in 736 career rushes, fewer than the previous quickest to this milestone (James in 755 career rushes).^[17]
• October 27 – LSU edged Alabama and Ohio State in one of the closest AP Poll votes ever. LSU received 1,476 points and 17 first-place votes from the voters, while Alabama received 1,474 points and 21 first-place votes and Ohio State received 1,468 points and 17 first-place votes. This 8-point margin between 1st and 3rd was the fewest since the current ranking system was remade in 1978.^[18]
• October 29 – The NCAA board of governors voted unanimously to begin the process of changing institutional rules so that college athletes can profit from their names, images, and likenesses, while still maintaining a distinction between college and professional sports. The proposal calls for each of the three NCAA divisions to draft new rules consistent with this mandate, with a target date of January 2021.^[19]
• November 5 — The first College Football Playoff committee rankings were released. The committee ranked Ohio State at No. 1, after the November 3 AP Poll ranked LSU at No. 1 and the November 3 Coaches Poll ranked Alabama at No. 1. This resulted in all three major college football selectors splitting on the number one team for the first time in the CFP era.

No. 3 Georgia (−20.5) falls to South Carolina in 2OT

On October 12, No. 3 Georgia Bulldogs (5–0, 2–0) played a home conference game against the South Carolina Gamecocks (2–3, 1–2). The Bulldogs, who had won five straight against the Gamecocks, were favored by 20.5 points. Though Georgia outgained South Carolina by more than 170 yards, they had four turnovers to South Carolina's none. Tied at 17, the game went to overtime, where, after Georgia failed to score on its possession, South Carolina had a chance to kick a game-winning 33-yard field goal. However, they missed it and the game went to a second overtime where South Carolina converted on a 24-yard field goal and Georgia missed a 42-yard field goal.^[33]

No. 6 Wisconsin (−30.5) defeated by Illinois on last second field goal

On October 19, No. 6 Wisconsin Badgers (6–0, 3–0) was heavily favored, by 30.5 points, against their conference rivals Illinois Fighting Illini (2–4, 0–2). The game was played at Illinois' stadium in Champaign, Illinois. Wisconsin led the entire game until a last second field goal was made by Illinois to give them a 24–23 win. Wisconsin turned over the ball on their last two drives which allowed Illinois to score twice in the last six minutes of the game. The Badgers had previously defeated the Fighting Illini in nine consecutive match-ups.^[34]

No. 5 Oklahoma's rally falls short against Kansas State (+23.5) after onside kick recovery overturned

On October 26, No. 5 Oklahoma Sooners (7–0, 4–0) traveled to the Kansas State Wildcats (4–2, 1–2) for a conference game. The Sooners were favored by 23.5 points and led 17–7 after the 1st quarter. However, Kansas State built a large 48–23 lead by scoring on 8 consecutive possessions, including scoring on each possession in the 2nd and 3rd quarters, after punting on its first possession of the game. In the 4th quarter, Oklahoma scored 18 consecutive points to cut the Kansas State lead to 48–41. After Oklahoma attempted an onside kick and appeared to recover it, the recovery was overturned due to an Oklahoma player touching the football prior to the ball traveling the required 10 yards. Kansas State was awarded possession of the ball and ran out the clock to preserve the Wildcats' first win over a top 5 team since 2006 and their first home win over Oklahoma since 1996.^[35][36]

No. 6 Oregon (−13.5) loses at Arizona State

On November 23, No. 6 Oregon Ducks (9–1, 7–0) traveled to the Arizona State Sun Devils (5–5, 2–5) for a conference game. The Ducks were favored by 13.5 points, but were behind at halftime 10–7. Arizona State stretched its lead to 24–7 with less than 9 minutes left in the 4th quarter, before 4 combined touchdowns scored in the final minutes allowed the Sun Devils to escape with a 31–28 victory.
