The 1997 Mountain Dew Southern 500, the 48th running of the event, was a NASCAR Winston Cup Series race held on August 31, 1997, at Darlington Raceway in Darlington, South Carolina. Bobby Labonte won the pole position and Jeff Gordon won the race for the third time in his career and clinched the Winston Million.

Darlington Raceway, nicknamed by many NASCAR fans and drivers as "The Lady in Black" or "The Track Too Tough to Tame" and advertised as a "NASCAR Tradition", is a race track built for NASCAR racing located near Darlington, South Carolina. It is of a unique, somewhat egg-shaped design, an oval with the ends of very different configurations, a condition which supposedly arose from the proximity of one end of the track to a minnow pond the owner refused to relocate. This situation makes it very challenging for the crews to set up their cars' handling in a way that will be effective at both ends.

The track is a four-turn 1.366 miles (2.198 km) oval.^[2] The track's first two turns are banked at twenty-five degrees, while the final two turns are banked two degrees lower at twenty-three degrees.^[2] The front stretch (the location of the finish line) and the back stretch is banked at six degrees.^[2] Darlington Raceway can seat up to 60,000 people.^[2]

Darlington has something of a legendary quality among drivers and older fans; this is probably due to its long track length relative to other NASCAR speedways of its era and hence the first venue where many of them became cognizant of the truly high speeds that stock cars could achieve on a long track. The track allegedly earned the moniker The Lady in Black because the night before the race the track maintenance crew would cover the entire track with fresh asphalt sealant, in the early years of the speedway, thus making the racing surface dark black. Darlington is also known as "The Track Too Tough to Tame" because drivers can run lap after lap without a problem and then bounce off of the wall the following lap. Racers will frequently explain that they have to race the racetrack, not their competition. Drivers hitting the wall are considered to have received their "Darlington Stripe" thanks to the missing paint on the right side of the car.

Dave Marcis, Greg Sacks and Morgan Shepherd all failed to qualify. The race had 11 cautions for 67 laps. Ernie Irvan had just gotten a lap back and as he was catching up to the field, the wrecked 12 of Jeff Purvis pulled down in front of Irvan and tore up the 28. It did damage to the cooling system and his pit stall was covered in water after every stop. He would eventually drop out of the race on lap 183 due to engine issues.^[3] A very odd instance of the race occurred when all the lead lap cars came in during the caution on lap 295 because of the nasty rain.^[3] Dale Jarrett was in the lead since lap 258 and his pit crew was telling him to stay out but for some reason he came in at the last second possible instead of staying out in case the race was called.^[3] Jeff Gordon came out in 1st after the pit stops and kept the lead for the last 72 laps that were left.^[3]

Dale Earnhardt suffered a blackout during the pace laps and crashed, ending his day. After the car was repaired, Busch Series driver Mike Dillon (the son-in-law of car owner Richard Childress) replaced him in the No. 3 car and got a 30th-place finish, 85 laps behind winner Jeff Gordon.^{[4][clarification needed]}

Several crashes and a brief instance of rain allowed the race to last for four hours and eight minutes. Gordon held off a late charge by Jeff Burton to win his ninth race of the year and the Winston Million by less than 0.2 seconds (his 28th overall).^[3] ESPN's Bob Jenkins called the ending thus:

Jeff Burton will make a challenge off the corner, onto the straightaway...but Jeff Gordon wins it!

The only other driver to have accomplished the Winston Million was Bill Elliott, who finished fourth and led the most laps. Rusty Wallace finished 43rd after a crash that collected Kyle Petty, Robby Gordon, and Todd Bodine on lap 5. He ended up with $29,270.^[3] The total winners' purse was $1,202,356 ($2,282,083.65 considering inflation). Gordon won $131,330 for winning plus an additional $1,000,000 for winning the Winston Million.^[5]
