Legend of the Galactic Heroes (銀河英雄伝説, Ginga Eiyū Densetsu?) is a series of science fiction novels by Yoshiki Tanaka. An anime adaptation of the novels ran from 1988 to 2000, and a manga is also based on the novels, with art by Katsumi Michihara.

Neither the novels, anime, nor manga have been released officially in the English language.

Set somewhere in distant space around the 35th century (the late eighth century of the story's "Space Era"), Legend of the Galactic Heroes is a story of the epic struggle between the monarchic Galactic Empire and the democratic Free Planets Alliance.

The original Japanese title is often abbreviated as Gin'eiden (銀英伝, Gin'eiden?) in Japan, while English-language fans often abbreviate the series title as LOGH (capitalization for the acronym varies).
