The Green Lantern Corps that appear in fictional stories published by DC Comics has at least 7200 members, two per sector (originally 3600 with one per sector), in addition to assorted other members who fulfill roles other than patrolling. Although seven characters—Alan Scott, Hal Jordan, Guy Gardner, John Stewart, Simon Baz, Kyle Rayner, and Jessica Cruz—are primarily associated with the name, a number of other members of the Corps have appeared in DC's comics.

These seven characters are most closely associated with the "Green Lantern" name, and have been the title characters of Green Lantern comics.

Alan Scott was the original Green Lantern character created in the Golden Age of comics. Alan created the mantle and identity of Green Lantern by himself and is not associated with the Green Lantern Corps, since his power ring was de-authorized by the Guardians even before his obtaining it. Prior to the Crisis Scott's ring ran on magic, and not the Central Power Battery of Oa. Today he is the modern day Green Lantern for New 52's earth 2.

Hal Jordan, known as Green Lantern, is a fictional superhero appearing in American comic books published by DC Comics. The character was created in 1959 by writer John Broome and artist Gil Kane, and first appeared in Showcase #22 (October 1959). Hal Jordan is a reinvention of a previous character called Green Lantern that had appeared in 1940s comic books as the character Alan Scott. Hal Jordan is a member and occasionally leader of the intergalactic police force called the Green Lantern Corps. He fights evil across the Universe with a ring that grants him a variety of superpowers.

Guy Gardner is a comic book superhero published by DC Comics. He is a core member of the Green Lantern family of characters, and for a time (late 1980s through mid 1990s) was also a significant member of the Justice League family of characters.[1] He was created by John Broome and Gil Kane (who patterned him after actor Martin Milner) in Green Lantern #59 (March 1968), although the character was changed significantly in the 1980s by Steve Englehart and Joe Staton who turned him into a jingoistic parody of an ultra-macho "red-blooded American male." This latter remains the character's archetype to this date.
