"Secret Invasion" is a comic bookcrossover storyline written by Brian Michael Bendis and illustrated by Leinil Francis Yu, that ran through a self-titled eight-issue limited series and several tie-in books published by Marvel Comics from April through December 2008. The story involves a subversive, long-term invasion of Earth by the Skrulls, a group of alien shapeshifters who have secretly replaced many superheroes in the Marvel Universe with impostors over a period of years, prior to the overt invasion. Marvel's promotional tagline for the event was "Who do you trust?".

A six-episode television miniseries of the same name, loosely based on the storyline and produced by Marvel Studios as part of the Marvel Cinematic Universe (MCU) debuted in June 2023 on Disney+.
