An epilogue or epilog (from Greek ἐπίλογος epílogos, "conclusion" from ἐπί epi, "in addition" and λόγος logos, "word") is a piece of writing at the end of a work of literature, usually used to bring closure to the work. It is presented from the perspective of within the story. When the author steps in and speaks directly to the reader, that is more properly considered an afterword. The opposite is a prologue—a piece of writing at the beginning of a work of literature or drama, usually used to open the story and capture interest. Some genres, for example television programs and video games, call the epilogue an "outro" patterned on the use of "intro" for "introduction".

Epilogues are usually set in the future, after the main story is completed. Within some genres it can be used to hint at the next installment in a series of work. It is also used to satisfy the reader's curiosity and to cover any loose ends of the story.
