Jeremy McWilliams (born 4 April 1964 in Belfast, Northern Ireland), is a motorcycle road racer. Until Scott Redding's win at the 2008 125cc British Grand Prix, he was the only rider from the British Isles to win a race or pole in an FIM MotoGP World Championship class in the 2000s.

For 2007, he was to race in the MotoGP series for the Ilmor team, despite a heavy crash in testing in late 2006. He had to miss the first race of the season in Qatar, due to another crash, near the end of the Losail International Circuit. After this round the team suspended its racing operations and has not returned. He is involved in development work for motorcycle and tyre manufacturers and also in coaching young riders through his Masterclass race schools.

In 2012, McWilliams participated in the North West 200 races, where he scored a second place in the Super-Twin event. Riding for the KMR Kawasaki Racing Team, McWilliams finished second behind his fellow Irishman Ryan Farquhar.

In 2013, McWilliams had a supporting role in the film Under the Skin, starring Scarlett Johansson.
