The 2014 Cotton Bowl Classic was a college football bowl game between the #9 Missouri Tigers of the Southeastern Conference and the #13 Oklahoma State Cowboys of the Big 12 Conference. The 78th edition of the Cotton Bowl Classic took place on January 3, 2014 at 8:00 p.m. EST and aired on FOX. It was one of the 2013–14 bowl games that concluded the 2013 FBS football season. AT&T Stadium, formerly known as Cowboys Stadium and located in Arlington, Texas, hosted the game for the sixth straight year. The game was sponsored by telecommunications company AT&T, and was officially known as the AT&T Cotton Bowl Classic.

The Tigers beat the Cowboys by a score of 41–31 to claim the school's second-ever Cotton Bowl Classic championship and set a new AT&T Stadium record with 24 points in the fourth quarter. This was the final Cotton Bowl Classic in the BCS Era, as the College Football Playoff was introduced to start the next season.

This was Missouri's third appearance in the Cotton Bowl Classic (their first as a member of the SEC) and Oklahoma State's fourth appearance. Missouri and Oklahoma State were previously conference rivals in the Big 12. In addition, the two teams shared a conference from 1925 to 1928 (when the conference was called the Missouri Valley Intercollegiate Athletic Association and would become the Missouri Valley Conference after that year) and again from 1958 to 2012 (still under the MVIAA name until 1964, then under the name Big Eight Conference from 1964 to 1996).
