List of American Championship Car winners

• The retroactively-awarded (unofficial) champions published by Haresnape & Means, and later Russ Catlin, are not reflected in the totals.
• Winners of the largely ceremonial USAC Gold Crown Championship (awarded from 1981 to 1995) are not included. During that period, the CART series conducted the national championship. Except for a dwindling "rump" period from 1980 to 1982, the Gold Crown title consisted of only the Indianapolis 500. Therefore, the Indy 500 winner was the de facto Gold Crown champion.
• Due to sanctioning body splits in the sport of American Open Wheel racing from 1979 to 2007, several years saw two separate champions awarded for separately sanctioned championship circuits. It is reflected in the table for 1979, and 1996–2007.
• Buzz Calkins and Scott Sharp tied for the three-race 1996 Indy Racing League championship. No rule existed to provide for a tiebreaker, and the two were declared co-champions.

A substantial number of non-championship races were sanctioned by the AAA Contest Board, namely from the periods from 1902–1904, 1906–1915, and 1917–1920. That includes the Indianapolis 500 in 1911, 1912, 1913, 1914, 1915, and 1919. Various other non-championship races have been conducted over the years by AAA, USAC, CART, and IRL from 1920–2008. The winners from those races are specifically not included in the main table above. Below is an abridged list of race winners from non-championship AAA races.

Notes

• The USAC Race of Two Worlds was considered a non-championship event. Likewise, the 1966 event at Fuji was a non-championship event. In some seasons, the Pikes Peak International Hill Climb was a championship event, and in some seasons it was not.
• CART conducted the Marlboro Challenge all-star race from 1987–1992. This was considered a non-championship event.
• Two INDYCAR races were abandoned as they were stopped before the legal definition of an official race by the sanctioning body, half distance plus one lap, unlike the FIA Code, which requires three green flag laps to be conducted for an official race. The 1999 IRL VisionAire 500K at Charlotte Motor Speedway was cancelled after 79 laps, and struck from record, with no winner officially declared following a Lap 62 crash where a tire went into the grandstand, killing three spectators. Buddy Lazier was leading at the time of the Lap 61 caution, while Greg Ray was leading at the formal race abandonment after Lap 79. The 2011 IZOD IndyCar World Championship at Las Vegas Motor Speedway was halted and formally abandoned after 11 laps as a result of a multiple-car crash that involved the death of Dan Wheldon, with Tony Kanaan leading. Therefore, the total number of IRL/IndyCar races reflected in the chart is two fewer than the number of actual events. Both races are recognised as "cancelled events" with the box scores listed based on standings at the time of abandonment on Racing Reference.
• In the aftermath of the open wheel unification in early 2008, due to a scheduling conflict, the 2008 Long Beach Grand Prix was contested with former Champ Car teams and chassis. It was uniquely regarded as the "final" Champ Car race. However, it was officially contested under IndyCar sanction, awarded points towards the IndyCar championship, and race winner Will Power is credited with an IndyCar victory to his credit from the event. Furthermore, the Nikon Indy 300 was included on the 2008 schedule as a non-points exhibition race. Therefore, race winner Ryan Briscoe was not credited with an official victory for that event.
• In 1952, another open wheel series was formed alongside the AAA, the NASCAR Speedway Division. Only one full season, along with a second partial season, was held, and the division folded after only ten points races. Of the ten race winners, none of the drivers (seven total) managed to win any races under AAA or USAC sanctioning.

This is an overview of which drivers have achieved a win on which race track. Only the number of different racetracks is displayed. Several victories on a particular track are not highlighted. The number of wins per driver is therefore smaller than the total number of his career victories.
