N or M? is a work of detective fiction by Agatha Christie first published in the US by Dodd, Mead and Company in 1941[1][2] and in the UK by the Collins Crime Club in November of the same year.[3] The US edition retailed $2.00[2] and the UK edition at seven shillings and sixpence (7/6).[3]

The title is taken from a catechism in the Book of Common Prayer which asks, "What is your Christian name? Answer N. or M."[4] The "N. or M." here stands for the Latin, "nomen vel nomina", meaning "name or names". It is an accident of typography that "nomina" came to be represented by "m".

The novel is the first to feature the mature versions of her detectives Tommy and Tuppence, whose previous appearances had been in the adventure The Secret Adversary (1922) and the short story collection Partners in Crime (1929).
