Frank Jerry Del Roy (born Frank De Rosa, November 7, 1912 – April 23, 1978) was an American auto racing official and race car builder.^[1][2]

After an early career as a riding mechanic, Del Roy worked in a purely off-track capacity for racers such as Ted Horn and Mike Nazaruk.^[2] In late 1955, the American Automobile Association – which through its Contest Board sanctioned Indy car and most other disciplines of auto racing in the United States – withdrew from racing. In 1958 Del Roy was hired as a technical official by the newly-formed United States Auto Club (USAC).

Del Roy's cars competed in one round of the FIA World Championship - the 1953 Indianapolis 500.

On April 23, 1978, Del Roy – by then Chairman of the USAC Technical Committee – along with a pilot and seven other USAC officials, was killed when his flight home from a race in Trenton, New Jersey crashed in a farm field south of Indianapolis, Indiana.^[1]
