Captain Charles Frederick Elsey CBE MC (10 December 1882 – 14 February 1966) was a British Thoroughbred racehorse trainer.
The son and father of successful trainers, Elsey was one of the dominant racing figures in the North of England, for more than thirty years in a career which lasted from 1911 until 1960.
He began training in 1911 at the Glasgow House Stable at Middleham, North Yorkshire, but abandoned his career in 1914 on the outbreak of the First World War.
Elsey won the title of British flat racing Champion Trainer for the first and only time at the end of the 1956 season at the age of seventy-four.
He retired from training in 1960 at the age of 78, leaving the Highfield Stable to his son Charles William Carlton "Bill" Elsey who had acted as his assistant trainer for several years.
