My Greatest Adventure was a DC Comics comic book that began in 1955 and is best known as the original title for the superhero team, the Doom Patrol.
The title was originally an anthology series with adventure stories told in the first person narrative. Over time the types of stories changed from simple adventure to science fiction. With issue #80 (June 1963), the anthology format was dropped and replaced with stories featuring the Doom Patrol. Issue #85 was the last to bear the My Greatest Adventure title; the series was renamed The Doom Patrol going forward from issue #86.
Issues #80-85 were reprinted as part of The Doom Patrol Archives, Vol. 1 (2002, ISBN 1-56389-795-4).
