Secret Origins is the title of three American comic book series published by DC Comics.
The title began in 1961 and was a one-off series containing all reprints. The title Secret Origins of Super Heroes (or Super Villains) went onto a second series, also reprints, which ran for seven issues from 1973-1974. Its most well-known incarnation was a 50-issue series (plus three annuals and a special) that ran from 1986 to 1990. Typically, an issue would be given over to clarifying the post-Crisis origins of a number of characters, usually two (as most of the issues were 'double-sized', i.e. 48 pages, plus ads). Roy Thomas was the initial writer/editorial consultant on the series; later issues were overseen by Mark Waid. Three more specials followed in 1998-1999. In 2004, it returned to the all-reprint format with a "Weird" special featuring Doctor Fate, The Spectre, Animal Man, Enchantress, Metamorpho, Congorilla, El Diablo, and Bizarro World.
