William Wheatley (1786-1848) was a British Classic winning jockey of the early 19th century.

Wheatley was booked to ride 50/1 outsider, Spaniel, a horse known for only possessing one steady pace.

[6] He was also known for having an untainted character,[5] and in Spaniel's Derby he had had a £25 bet at odds of 40/1 on his mount winning, only to cancel it at the last minute, thereby missing out on £1000.

One of his most noted rides was in the "ever-memorable" Ascot Gold Cup when he rode Mameluke against Zinganee, ridden by Sam Chifney, Jr.[3] His principal patron was Lord Lowther.

William Wheatley lived up to the 1840s at Newmarket where his father and family had settled but died at Kingsland, then a small settlement in Middlesex but now part of Hackney, in February 1848 aged about 62.
