750 Motor Club is an motor racing club in the UK. It was founded in 1939 to promote the sporting use of the Austin 7. (750 refers to the 750cc Austin 7 engine). It later led to racing and the 750 Formula where specials were raced. Famous members include Colin Chapman, and Eric Broadley.

The 750MC has continued to promote low-cost racing for enthusiasts, with a range of championships for production and racing sports cars, saloons and single-seaters.
