William Day (1823–1908) was a British Jockey and Trainer. A member of a large and highly successful racing family Day had limited success as a jockey before setting up as a trainer at Woodyates in 1848. In a training career of over thirty years Day sent out the winners of three classics and numerous important handicap races before retiring in the 1880s. His best horse was probably the American colt Foxhall.
