X-Men: First Class is a comic book series published by Marvel Comics starring the X-Men.The concept is in production as a film of the same name.

The original series was an eight-issue limited series. It began in September 2006 and ended in April 2007. It was written by Jeff Parker and penciled by Roger Cruz. It was followed by a special issue in May 2007 and a monthly series that premiered in June 2007 with the same creative team.

Many of the series' stories are done in single issues, some are two-parters and multiple issue arcs. The original team of X-Men are wearing new costumes in the series. The series guest-stars many other characters, such as Lizard, Quicksilver, Scarlet Witch, Man-Thing, Gorilla-Man, Doctor Strange, Invisible Woman and Thor.

The series has spawned a few spin-offs, titles including the ongoing series Wolverine: First Class, and the miniseries Weapon X: First Class.

The ongoing series lasted sixteen issues and it was followed by Giant-Size X-Men: First Class special issue. Starting February 2009, a four issue miniseries titled X-Men: First Class Finals will encompass volume 3. This ends with the team going on to the Krakoa island mission.

A new volume called Uncanny X-Men: First Class premiered in the August 2009 one-shot Uncanny X-Men: First Class Giant-Sized. The new series will concentrate on the team first introduced originally back in Giant-Sized X-Men #1.
