List of American Championship Car winners

The following is a list compiling the total number of career victories in open wheel American Championship car racing. The list recognizes "Indy car" or "Champ car" victories under the following auspices:

The AAA Contest Board began sanctioning races as early as 1904. In the early years of the sport, only two seasons (1905 and 1916) an official national championship was recognized and awarded. Individual events from 1904, 1906–1915, and 1917–1919 are specifically excluded from the table below, due to the fact that they were not part of an official "championship" season.

The national championship was re-instated by AAA for 1920 and beyond. Retroactively awarded titles for the other years were later researched, although most historians consider them to be revisionist, and do not deem them as suitable for official record. All racing was suspended from 1942 to 1945, due to WWII. The 1946 season is a source of a statistical anomaly. The AAA Contest Board included a substantial number of "Big Car" races in the national championship for 1946, swelling the season to 77 events (6 Champ Car races and 71 Big Car races). Some later texts chose to dismiss the 71 Big Car races from record, but reliable records and historians contend that the season should be regarded as the full 77-race schedule.

Note that victories in the Indianapolis 500 from 1979 to 1995 are listed under the heading of USAC. While CART sanctioned the primary year-long season of races, the Indianapolis 500 itself remained under the sanctioning of USAC.

For 1996–1997, victories in the Indianapolis 500 and Indy Racing League are listed solely under the heading of IndyCar. For the first nine races of its existence (five in 1996 and four in 1997), the Indy Racing League fell under the sanctioning umbrella of USAC. After two controversial races in early 1997, sanctioning abruptly switched to in-house oversight by the IRL. In 2010, the series retired the term "IRL" in favor of "IndyCar."
