Eric O'Grady is the name of two characters appearing in American comic books published by Marvel Comics. The first is an immoral Irish human superhero who is the third character to use the Ant-Man name, created by writer Robert Kirkman and artist Phil Hester, and first appears in The Irredeemable Ant-Man #1 (December 2006), while the second is a Life Model Decoy made of the original O'Grady's corpse created after his death, revived with a more outwardly villainous mindset and initially continuing as Ant-Man before becoming the supervillain Black Ant, created by writer Rick Remender and artists Gabriel Hardman and Matteo Scalera, and first appearing in Secret Avengers #24 (March 2012).

Publication history 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. The final issue mocked the idea of cancellation while concluding its main storyline, such as having O'Grady 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 Hank 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's corpse was used to create a Life Model Decoy (LMD) with all of his memories in the following issue, who renaming himself the Black Ant in issue #32 on his status as an LMD being revealed, revealing himself as an antagonist in issue #36, before disappearing in his final issue #37 (March 2013). Over the 2010s and 2020s, Black Ant returned in supporting roles as a supervillain and henchman.
