Tarrare was a bay Thoroughbred racehorse stallion, foaled in 1823. He is known for winning the 1826 Doncaster St. Leger and the Doncaster Cup. He was the first winner of the Doncaster St. Leger after the course had been altered by being slightly shortened and the starting gate widened. The race was notable for having the first and second place horses sired by the same horse, a noted racing stallion named Catton. His bloodline also includes Eclipse, Matchem, and Herod. Tarrare was ridden in the St. Leger by jockey George Nelson, trained by the Earl of Scarborough.
