Deadlier Than the Male is a 1967 British crime and mystery film directed by Ralph Thomas and starring Richard Johnson and Elke Sommer. It is one of the many take-offs of James Bond produced during the 1960s, but is based on an already established detective fiction hero, Bulldog Drummond.

Drummond, updated to a suave Korean War veteran, trails a pair of sexy assassins who kill for sport and profit.

The title is a reference to the 1911 Rudyard Kipling poem The Female of the Species, which includes the line, "The female of the species must be deadlier than the male", and also refers to Sapper's earlier Drummond book, The Female of the Species.

A sequel, Some Girls Do, followed in 1969.
