An autograph is a document transcribed entirely in the handwriting of its author, as opposed to a typeset document or one written by an amanuensis or a copyist; the meaning overlaps with that of the word holograph.

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

What might be considered the oldest "autograph" is a Sumerian clay table from about 3100 BC which includes the name of the scribe Gar.

Ama. No ancient written autographs have been found, and the earliest one known for a major historical figure is that of El Cid from 1098.
