The endpapers or end-papers of a book are the leaves of paper before the title page and after the text. Booksellers sometimes refer to the front end paper as FEP.

Before mass printing in the 20th century it was common for the endpapers of books to have paper marbling. Sometimes the endpapers are used for maps or other relevant information. They are the traditional place to put bookplates, or an owner's inscription.

As of 2010 there are many styles of endsheets or endpapers that are specifically designed for use with different bindings. Read more on the history of endpapers.
