Leo James Mansell[1] (born 4 January 1985 on the Isle of Man) is a British racing driver.

He is the son of 1992 Formula One world champion and 1993 PPG Indy Car World Series champion, Nigel Mansell, and elder brother of fellow racing driver Greg Mansell.

The brothers ascended through the Karting ranks, and moved into single-seater racing in 2006, in the Formula BMW UK series.

Mansell, with his father Nigel, tested a Chamberlain-Synergy team Le Mans prototype Lola-AER B06/10 during the week commencing 14 July 2008 at the Estoril circuit.

At the 8 Hours of Castellet they finished 9th overall (8th in LMP1), but their Le Mans effort was cut short due to a tyre failure and a crash by Nigel early in the event.
