The 1991 Miller Genuine Draft 500 was the 16th stock car race of the 1991 NASCAR Winston Cup Series season and the 19th iteration of the event. The race was held on Sunday, July 21, 1991, in Long Pond, Pennsylvania, at Pocono Raceway, a 2.5 miles (4.0 km) triangular permanent course. The race was shortened from its scheduled 200 laps to 179 laps due to rain. In the final laps of the race, Penske Racing South driver Rusty Wallace would manage to conserve enough fuel to run until the last caution flag was given on lap 174. After the red flag was given out on lap 176, a two-hour rain delay would delay the restart. After the rain delay, NASCAR mandated that all drivers start their cars and run behind the pace car until lap 179, where NASCAR would declare the race official, handing Wallace the victory. The victory was Wallace's 20th career NASCAR Winston Cup Series victory and his second and final victory of the season. To fill out the top three, Roush Racing driver Mark Martin and Junior Johnson & Associates driver Geoff Bodine would finish second and third, respectively. Background The race was held at Pocono International Raceway, which is a three-turn superspeedway located in Long Pond, Pennsylvania. The track hosts two annual NASCAR Sprint Cup Series races, as well as one Xfinity Series and Camping World Truck Series event. Until 2019, the track also hosted an IndyCar Series race.

It is operated by the Igdalsky siblings Brandon, Nicholas, and sister Ashley, and cousins Joseph IV and Chase Mattioli, all of whom are third-generation members of the family-owned Mattco Inc, started by Joseph II and Rose Mattioli. Outside of the NASCAR races, the track is used throughout the year by the Sports Car Club of America (SCCA) and motorcycle clubs as well as racing schools and an IndyCar race. The triangular oval also has three separate infield sections of racetrack – North Course, East Course and South Course. Each of these infield sections use a separate portion of the tri-oval to complete the track. During regular non-race weekends, multiple clubs can use the track by running on different infield sections. Also some of the infield sections can be run in either direction, or multiple infield
