Kayf Tara (18 March 1994 – 8 December 2022) was a British Thoroughbred racehorse and sire.
His dam Colorspin won the Irish Oaks and had previously produced the multiple Group One winner Opera House.
The recurrence of an old injury brought Kayf Tara's racing career to an end.
Kayf Tara won the Cartier European Top Stayer three years in a row from 1998 to 2000.
