The 1988 Budweiser 400 was the 12th stock car race of the 1988 NASCAR Winston Cup Series season, the third race of the 1988 NASCAR Winston West Series, and the 20th and final iteration of the event. The race was held on Sunday, June 12, 1988, before an audience of 72,000 in Riverside, California, at the short layout of Riverside International Raceway, a 2.62 miles (4.22 km) permanent road course layout at the track. The race took the scheduled 95 laps to complete. Following an initial scoring error, Blue Max Racing driver Rusty Wallace would manage to pull away on the final restart with five laps left in the race to take his fifth career NASCAR Winston Cup Series victory and his first victory of the season. To fill out the top three, Junior Johnson & Associates driver Terry Labonte and King Racing driver Ricky Rudd would finish second and third, respectively.
The race was the final NASCAR Winston Cup Series race held at Riverside International Raceway before the track's closure in 1989.
