Automobile Racing Club of America (ARCA) is an auto racing sanctioning body in the United States founded in 1953 by John Marcum. The current president of ARCA is Ron Drager. ARCA (aka the ARCA RE/MAX Series) races stock cars similar to those seen in the NASCAR Nationwide Series, and indeed most cars used in ARCA were previously used in NASCAR. ARCA's competitors contain a mix of both professional racers as well as hobby racers alike, in addition to younger competitors trying to make a name for themselves, sometimes driving as part of a driver development program for a NASCAR team.

ARCA also sanctions a truck racing series called the ARCA Lincoln Welders Truck Series and owns the Toledo Speedway and Flat Rock Speedway. Formerly sanctioned the ARCA Midget Series from 1988 until 2002.
