X-Men Forever is the name of three comic book series published by Marvel Comics featuring the mutant superhero group the X-Men. The first is a 2001 miniseries, unrelated to the others. The second and third are the work of writer Chris Claremont.

Christopher S. Claremont is an American comic book writer and novelist, known for his 16-year stint on Uncanny X-Men from 1975 to 1991, far longer than that of any other writer, during which he is credited with developing strong female characters as well as introducing complex literary themes into superhero narratives, turning the once underachieving comic into one of Marvel's most popular series.
