"An Episode of Cathedral History" is a ghost story by the English writer M. R. James, first published in The Cambridge Review on 10 June 1914, and later collected in his books A Thin Ghost and Others (1919) and The Collected Ghost Stories of M. R. James (1931). Sometimes considered a work of vampire fiction, it concerns an incident in Southminster in 1840 where the renovation of a cathedral choir results in the emergence of a malicious creature from a fifteenth century altar-tomb.
