The Moon Endureth, subtitled 'Tales and Fancies', is a 1912 short story and poetry collection by the Scottish author John Buchan.

In an introduction to the collection Buchan quotes from an article on St Francis in Lives of the Saints: "To the righteous is promised abundance of peace while the moon endureth".
