Green Arrow is a fictional character, published by DC Comics. Created by Mort Weisinger and George Papp, he first appeared in More Fun Comics #73 in 1941. His secret identity is Oliver Queen, billionaire and former mayor of fictional Star City; he is best known to his associates as Ollie.

Dressed like Robin Hood, Green Arrow is an archer, who invents trick arrows with various special functions, such as a glue arrow, a net arrow, explosive arrow, time bomb arrow, grappling arrow, fire extinguishing arrow, flash arrow, tear gas arrow, cryonic arrow, or a boxing-glove arrow.

Throughout his first twenty-five years, Green Arrow was not a significant hero. In the late 1960s, however, writers chose to have him lose his fortune, giving him the then-unique role of streetwise crusader for the working class and the disadvantaged. In 1970, he was paired with the more law-and-order-oriented hero Green Lantern in a groundbreaking, socially conscious comic book series. Since then, he has been popular among comic book fans and most writers have taken an urban, gritty approach to the character.

His son Connor Hawke also used the moniker Green Arrow for a time after the death of Oliver Queen.
