The Pocono 500 was an IndyCar Series race held at Pocono Raceway in Long Pond, Pennsylvania, located in the Pocono Mountains. The first Indy car race at Pocono was held in 1971. It was the first major event held at the track, shortly after its completion. The race was sanctioned by USAC from 1971 to 1981, and then by CART from 1982 to 1989, and was known as the Pocono 500. The race was removed from the CART calendar following the 1989 running, due to poor track conditions, as well as poor revenue for the promoter.
