Ralph Crockett (b. at Barton, near Farndon, Cheshire 1522; executed at Chichester, 1 October 1588) was an English Roman Catholic priest.

Educated at Christ's College, Cambridge,[1] Crockett became a schoolmaster in Norfolk for a year before going to Gloucester Hall, Oxford.

He was ordained at Rheims in 1585, and continued his studies for a year, but his health being compromised, he asked to return to England.

He and three other priests, Thomas Bramston, George Potter, and Edward James, left from Dieppe, but the ship ran ashore 19 April 1586 at Littlehampton, Sussex, a place as carefully watched as any in the kingdom.

Crockett and James with two others, John Oven and Francis Edwardes, were selected for trial, which took place at Chichester on 30 September 1588.
