He will not be attending the Oscars on March 4, ending months of speculation over whether the Academy Award-winning actor would be a disruptive presence at the ceremony during a season dominated by the #metoo campaign.
Affleck, 42, won the Oscar last year for his performance in Manchester By The Sea and, by academy tradition, the best actress statuette is handed out by the previous year's best actor winner.
He triumphed then, despite two women suing him for sexual harassment during the production of the 2010 film, I'm Still Here, which he directed. He reached a settlement with them.
In the current climate, Affleck decided his presence at the Academy Awards would be untenable, according to Deadline Hollywood.
He felt that the focus should be on the women up for best actress and their performances, and not him.
