"Age of X" is a comic book storyline published by Marvel Comics as part of its X-Men series. The storyline is set in an alternate reality known as Earth-11326. Running from January to April 2011, it is similar in name and tone to the 1995 "Age of Apocalypse" (AoA) storyline.

After the announcement of the storyline in December 2010, Marvel added QR code on selected comics. These codes were linked to five different historical logs, each providing background for the "Age of X".

The mutants are almost extinct, tortured by a strike force led by Colonel Graydon Creed. The first signs of the Age of X appeared in X-Men: Legacy #244; the events were removed from the Earth-616 mainstream continuity, with no memories of the alternate lives.

The primary event occurs 1,000 days who fakes their deaths and explains that he sent Shadowcat out to investigate because he is convinced something is wrong. As Magneto returns to the brig to free Shadowcat and Professor X, X (the voice controlling Fortress X) sends the Cadre after him. Gambit and Legacy (who are in the room at the center of the fortress) discover that their universe has been stolen and is kept in a box. When Professor X is freed, he telepathically shows his pursuers and a reluctant Legion the truth about himself and the reality in which they think they are living. The Age of X was created when Legion's mind reacted to Doctor Nemesis's attempt to restore it to sanity. A new persona (with new powers) was born, creating a new reality to protect Legion's personalities. This manifestation of Legion's power assumed the appearance of Moira MacTaggert to confuse Xavier and protect Legion. Moira confronted Legacy and Gambit, revealing that she is also X. Cornered by Xavier, X launches a last offensive on the fortress.
