Ladkin (foaled 1921 in Kentucky) was an American Thoroughbred racehorse bred and raced by August Belmont, Jr. Out of the dam, Lading, he was sired by Fair Play who also sired Man o' War.

Ladkin is best remembered in racing for his win over the European star Epinard in the 1924 International Special No.2 at Aqueduct Racetrack in Queens, New York.

Following the death of August Belmont, Ladkin was purchased by the racing partnership prominent businessmen, W. Averell Harriman and George Herbert Walker who raced in him in 1925 under the nom de course, Log Cabin Stable.

Injured the previous October, in 1925 Ladkin met with little racing success and in October was retired to stud duty at the Nursery Stud near Lexington, Kentucky.
