The Firestone Indy 225 was an IndyCar racing event held at Nazareth Speedway from 1987–2004. From 1987–2001, the event was sanctioned by CART. In 2002, the race switched to the Indy Racing League. From 1987–1996, the race was scheduled for 200 laps. In 1997, the race was lengthened to 225 laps. Rising speeds had led to the races being completed very quickly, and CART officials worried that the fans were not getting their money's worth. The race was discontinued after the track closed permanently in 2004.

The 1987 CART PPG Indy Car World Series season was the 9th national championship season of American open wheel racing sanctioned by CART. The season consisted of 16 races, and one non-points exhibition event. Bobby Rahal was the national champion, winning his second-consecutive title. The rookie of the year was Fabrizio Barbazza. The 1987 Indianapolis 500 was sanctioned by USAC, but counted towards the CART points championship. Al Unser won the Indy 500, his record-tying fourth victory at Indy.
