Jack Sears (16 February 1930 – 6 August 2016) was a British race and rally driver, and was one of the principal organisers of the 1968 London-Sydney Marathon.

He won the inaugural British Saloon Car Championship in 1958, driving an Austin Westminster.

After finishing on joint maximum points with Tommy Sopwith, it was initially suggested the champion would be decided by the toss of a coin.

The idea was very unpopular with both drivers and at the final meeting at Brands Hatch, with a draw being a likely possibility, two identical looking Marcus Chambers-owned Riley One-Point-Five works rally cars were brought along for a five lap shoot-out.
