The 1973 Rebel 500 was a NASCAR Winston Cup Series race that took place on April 15, 1973, at Darlington Raceway in Darlington, South Carolina.

Three hundred and sixty seven laps took place on the paved oval track spanning 1.366 miles (2.198 km) for a total of 501.3 miles (806.8 km).^[2][3][4] The total time of the race was four hours and four minutes.^[2][4] Speeds were: 122.655 miles per hour (197.394 km/h) for the average and 153.463 miles per hour (246.975 km/h) for the pole position.^[2] There were eleven cautions for seventy-one laps.^[2][3][4] David Pearson defeated Benny Parsons by thirteen laps in front of forty-eight thousand people.^[2][3][4]

Early in the race on lap 2, a 5 car accident happened in Turn 2. Buddy Arrington, Richie Panch, Dave Marcis, Lennie Pond, and Dean Dalton were involved. Marcis and Pond would eventually go on to retire due to crash related problems.^[5] Cale Yarborough would suffer a spin also early in the race. Paul Tyler and Bobby Issac would also spin in the race. James Hylton would smash into the wall, causing a caution. Charlie Roberts would also suffer engine failures, causing another caution. The 10th caution would come out with an accident including Cale Yarborough and G.C. Spencer. With Pearson leading the next restart, it only took one turn to turn Turn 1 into a "junkyard", with a 7 car crash, including Parsons, Petty, Arrington, Mayne, Brooks, and more involved, causing the 11th caution. Twelve cars finished this race out of the 40 starters.

This race stands as the second largest margin of victory in Cup history, falling just short of Ned Jarrett and his 14 lap differential in the 1965 Southern 500.^[2][3][4]
