Phil Bull (9 April 1910 – 11 June 1989), born West Yorkshire, England, was a professional gambler, racehorse owner and publisher, who founded the Timeform private handicapping system for British horseracing. Since 1948, Timeform have produced performance ratings for every racehorse in Great Britain and, increasingly, internationally. Timeform ratings have become adopted as the British horseracing industry's unofficial, but authoritative, measure of racehorse performance. It was said of Bull in 1976 that "there is no more familiar figure on English racecourses than the stocky, bearded one of Mr Phil Bull". Many racing aphorisms can be attributed to Bull, such as "at the racecourse, keep your eyes open and your ears closed".
