Tattenham Corner is a neighbourhood in north Surrey, UK, but the name is principally associated with Epsom Racecourse.

Tattenham Corner refers to the sharp bend in the track at the eastern (upper) part of Epsom Racecourse and its immediate vicinity, which includes Tattenham Corner railway station, a few shops and a branch library. The racecourse itself and a short length of road between the station and the course are in the borough of Epsom & Ewell. The remainder of the local area, which is residential and has a high proportion of Central London commuters, is known as Tattenhams or Great Tattenham and Little Tattenham, and is in Tattenhams ward of Reigate & Banstead.
