The Treasure of Abbot Thomas is a short film which serves as the fourth episode of the British supernatural anthology television series A Ghost Story for Christmas. Written by John Bowen, produced by Rosemary Hill, and directed by the series' creator, Lawrence Gordon Clark, it is based on the ghost story of the same name by M. R. James, first published in the collection Ghost Stories of an Antiquary (1904), and first aired on BBC1 on 23 December 1974.

It stars Michael Bryant as the academic Rev. Justin Somerton, who along with his protoge Peter, Lord Dattering (Paul Lavers) seeks to uncover the supposed resting place of a cache of gold which once belonged to Abbot Thomas (John Herrington), a disgraced 15th century alchemist. It is the first entry in the series to feature original music, composed by Geoffrey Burgon.
