Harlequin is the name of four clown-themed DC Comics characters.

The original Harlequin was a foe of the Golden Age Green Lantern, and later became his wife. The second Harlequin originally debuted as the Joker's Daughter, and was a member of the Teen Titans. The third Harlequin was a member of the Injustice Unlimited super-villain team, and battled Infinity, Inc. The fourth Harlequin has only appeared on a few occasions, and is an enemy of Alan Scott. The Harlequin was ranked 100th in Comics Buyer's Guide's "100 Sexiest Women in Comics" list, although this list does not specify which version of the character was chosen.

The Molly Mayne version of Harlequin first appeared in All-American Comics #89 and was created by Robert Kanigher and Irwin Hasen.

The Marcie Cooper version of Harlequin first appeared in Infinity, Inc. and was created by Roy Thomas.

The unidentified Harlequin first appeared in Green Lantern Corps Quarterly #5 and was created by Ron Marz and Jim Balent.

The original Harlequin was Molly Mayne who appeared in stories alongside the Golden Age Green Lantern (Alan Scott).

Mayne developed a crush on Scott and, donning a colorful costume (which included harlequin glasses, a conical hat, and a mandolin), started a life of crime to attract his attention. Her crimes tended to be harmless and mostly for show, although the two clashed on several occasions in the late 1940s.

She briefly joined the Injustice Society until she turned on them by aiding the Justice Society of America. She had a deep running altruistic streak which occasionally led her to join forces with her enemy/would-be love interest. Despite being attracted to Harlequin, Scott never entered into a relationship with her and she eventually gave up in despair. She made a deal with the government in which she went on intelligence missions in return for amnesty for her past crimes and then quietly retired. On one occasion, she assisted Green Lantern, Superman and Lois Lane in capturing another foe of her love, the Sportsmaster.
