Immortal was a heel professional wrestling alliance in Total Nonstop Action Wrestling (TNA). It originally consisted of leaders Eric Bischoff and Hulk Hogan, as well as Abyss, Jeff Hardy and Jeff Jarrett, and later also came to include Bully Ray, Chris Harris, Gunner, Kurt Angle, Matt Hardy, Mr. Anderson, Murphy, Ric Flair, Rob Terry, Scott Steiner, and Tommy Dreamer as well as the members of the formerly separate stable Fortune. Referee Jackson James and valet Karen Jarrett were also affiliated with the group. Jeff Hardy was a two-time TNA World Heavyweight Champion, while Anderson and Angle were one-time TNA World Heavyweight Champions as members of the stable, and Jarrett was also a one-time holder of the AAA Mega Championship in the Mexican promotion AAA. The group's name was derived from Hogan's long-standing nickname "The Immortal".
