Frank Stallworth Lockhart (born April 8, 1903 at Dayton, Ohio - April 25, 1928 at Daytona Beach, Florida) was an American automobile racing driver active in the 1920s, considered by many historians to be a legend in the sport on par with 1960s British World Driving Champion Jim Clark.
During a "remarkable if all too short" career, Lockhart won numerous races on dirt, board tracks, the 1926 Indianapolis 500, and set a world land speed record for a distance average.
In all, he had nine AAA wins and two vice-championships in two years of competition.
