Frontier (foaled 1896) was a British Thoroughbred racehorse who won the Dewhurst Plate as a two-year-old and the Ascot Derby as a three-year-old.

He was the son of dual Eclipse Stakes winner Orme, who was Champion sire in Britain in 1899.

As a two-year-old Frontier ran in the National Breeders' Produce Stakes over five furlongs at Sandown.

After the start Frontier was on his own of the far side of the track and as the horses neared the finish he and Caiman, the 11/8 favourite, came away from the field.

[6] In the Eclipse Stakes at Sandown he faced 2000 Guineas and Epsom Derby winner Flying Fox, who started as the 14/100 favourite.
