World's Finest Comics was a comic book series published by DC Comics from 1939 to 1986. The series was initially titled World's Best Comics for issues 1-9; issue #10 (1941) switched to the more prominent name. Every issue featured DC's two leading superheroes, Superman and Batman. The series was initially a 60 page bi-monthly anthology, featuring various DC characters - always including Superman and Batman - in separate stories. When superheroes fell out of vogue in the 1950s, DC shortened the size of the publication to that of the rest of its output, leaving only enough space for one story; this led to Superman and Batman appearing in the same story together starting with World's Finest #71 (1954). The series continued in this vein until its cancellation in 1986 at #323.

A number of World's Finest titles have since appeared:

• a three-issue Legends of the World's Finest miniseries in 1994, spinning off of the popular Legends of the Dark Knight anthology
• a two-issue Superboy/Robin: World's Finest Three in 1996
