One Million A.D. is a science fiction anthology edited by American writer Gardner Dozois, published in 2005.
The book may be the first anthology of stories focused on the far future.
The contents, made up of six novellas, were commissioned for this book and published here for the first time. The book also begins with a three-page introduction by Dozois.
The setting of Reynolds's story was later used as the setting for the novel House of Suns.
