The Unnamable is a 1953 novel by Samuel Beckett. It was originally published in French as L'Innommable and later translated by the author into English. Grove Press published the English edition in 1958.

Samuel Barclay Beckett was an Irish novelist, dramatist, short story writer, theatre director, poet, and literary translator. His literary and theatrical work features bleak, impersonal, and tragicomic experiences of life, often coupled with black comedy and nonsense. His work became increasingly minimalist as his career progressed, involving more aesthetic and linguistic experimentation, with techniques of stream of consciousness repetition and self-reference. He is considered one of the last modernist writers, and one of the key figures in what Martin Esslin called the Theatre of the Absurd.
