An autograph (from the Greek: αὐτός, autós, "self" and γράφω, gráphō, "write") is a document written entirely in the handwriting of its author, as opposed to a typeset document or one transcribed by an amanuensis or a copyist; the meaning overlaps with that of the word holograph.

Autograph also refers to a person's signature. This term is used in particular for the practice of collecting autographs of celebrities. The hobby of collecting autographs is known as philography.
