80-Page Giant was the name used for a series of comic books published by DC Comics beginning in 1964. The series was named for its unusually high page count (32 pages being the norm for American monthly comics at this time). The cover price was typically 25 cents (other comics of the day which were rarely above twelve cents). Many of these Giant issues contained reprinted material, often including material from the Golden age era of comics. Each issue would focus upon a particular DC character or group, such as Superman, Batman, or Jimmy Olsen. The 80-Page Giant format and numbering would later be used for special extra-large, reprint-heavy issues of their regularly published titles.

In the late nineties, DC Comics began publishing 80-Page Giant specials which were special publications relating to a series (including Secret Origins, which had not been an ongoing title for years) and which were usually compilations.
