# 1912 AAA Championship Car season

The 1912 AAA Championship Car season consisted of 18 races, beginning in Santa Monica, California on May 4 and concluding in Brooklyn, New York on November 5. There was also one non-championship event at Milwaukee, Wisconsin. AAA did not award points towards a National Championship during the 1912 season, and did not declare a National Champion. Joe Dawson was the winner of the Indianapolis 500.
The de facto National Champion as polled by the American automobile journal Motor Age, was Ralph DePalma. Points were not awarded by the AAA Contest Board during the 1912 season. DePalma was named the champion by Chris G. Sinsabaugh, an editor at Motor Age, based upon merit and on track performance. A points table was created retroactively in 1927. At a later point, it was recognized by historians that these championship results should be considered unofficial.
