Thomas Pilchard (Pilcher) (born at Battle, Sussex, 1557; executed at Dorchester, 21 March 1587) was an English Roman Catholic priest.

He became a Fellow of Balliol College, Oxford, in 1576, and took the degree of M.A., in 1579, resigning his fellowship the following year.

In London on business, he was recognised by someone who knew him from Oxford and was arrested early in March 1587, and imprisoned in Dorchester Gaol.

Executions for treason being rare in that part of the county, there was some difficulty finding anyone to carry out the sentence.

"[1] Thomas Pilchard is commemorated with the Dorset Martyrs memorial on Gallows Hill, Dorchester.
