The 2002 American Le Mans Series season was the 32nd season for the IMSA GT Championship, and the fourth under the American Le Mans Series banner.
Following the demise of the European Le Mans Series, the North American schedule was greatly expanded to ten races.
Several temporary street courses were added in cities such as Miami, Florida and Washington D. C., while the Portland International Raceway and Texas Motor Speedway did not return, leaving the ALMS without any road course ovals on the schedule.
Circuit Trois-Rivières joined Mosport as a second Canadian event, and Road America was also scheduled for the first time.
Teams only score the points of their highest finishing entry in each race.
