Catacombs (U.S. title: The Woman Who Wouldn't Die) is a 1965 British horror film directed by Gordon Hessler and starring Gary Merrill, Georgina Cookson and Jane Merrow.

An astute business woman is murdered by her husband who intends to carry on with his affair with her niece after her death.

The film was shot at Shepperton Studios with sets designed by the art director George Provis.

The preliminaries setting the domestic scene are much too long, but after the murder things perk up considerably, with one or two nice macabre effects.
