Mid-America Raceway was a road racing circuit and dragstrip, located in Wentzville, Missouri, near St. Louis, built in 1964, and used until 1992.

It hosted various SCCA races, as well as Trans-Am and IMSA GT races.

After the circuit was no longer being used, the 1,200 foot portion that doubled as a drag strip continued to be used until October 31st, 2004.

In 2005 it was sold to a developer, after facing years of hostility from the neighboring homes that had built on property adjoining the race track.
