Eric O'Grady is a fictional character in the Marvel Comics Universe. The fourth character to use the Ant-Man name, he was created by Robert Kirkman and Phil Hester, and first appears in Irredeemable Ant-Man #1 (December 2006).

Eric O'Grady was the main character in the ongoing monthly series The Irredeemable Ant-Man, with the "Irredeemable" title given to the comic's title to indicate the character's immoral attitude and behavior. The series was canceled after issue #12, though no official cancellation notice was given (as Marvel Comics simply opted to not solicit issues of The Irredeemable Ant-Man beyond #12, though the final issue did mercilessly mock the idea of cancellation, such as having Eric scream in spite towards a massive assault of canceled comic characters).

Though canceled, the series ended with the character becoming enrolled in the Initiative. With Avengers: The Initiative #8, O'Grady joined the title's cast. He departed from the title after Avengers: The Initiative #20, and as of Thunderbolts #128, is a member of the new Thunderbolts team. After the events of Siege, he becomes a member of the Secret Avengers, beginning with issue one. Beginning in November 2010, he starred alongside Henry Pym in the three-issue mini-series Ant-Man and the Wasp, by Tim Seeley.

Ant-Man appeared as a regular character throughout the 2010–2013 Secret Avengers series, from issue #1 (July 2010) through the character's death in issue #23 (April 2012); the character was replaced by a Life Model Decoy with all of his memories in the following issue, renaming itself the Black Ant in issue #32, revealing itself as an antagonist in issue #36, before disappearing in its final issue #37 (March 2013).
