Gineipaedia is a collaborative encyclopaedia devoted to Legend of Galactic Heroes, the science-fiction franchise known for its interstellar conflicts, political factions, characters, and adaptations. Created as a community-editable resource, the wiki contains more than 1,400 articles covering the original animated series and related works, including Legend of Galactic Heroes Gaiden, Die Neue These, manga, novels, and films. Its reference material ranges from biographies and locations to military ranks, technology, timelines, and information about the Free Planets Alliance, Galactic Empire, Fezzan, and other settings.

Visitors can also explore featured articles, translation resources, policy guidance, staff information, and lists of pages needing work. The site warns readers that its content includes spoilers. Gineipaedia is no longer open to contributions: it was closed on 24 December 2024 and preserved as a static archive.

It therefore serves as a read-only reference for fans seeking organized information about the franchise, rather than an active community publishing new edits
