Sage, real name Teresia Karisik, is a character appearing in American comic books published by Marvel Comics. She has most often been associated with the X-Men and the Hellfire Club, whom she spied upon under the alias Tessa for Charles Xavier.

A mutant, Sage possesses a number of mental abilities and was presented as the personal assistant to the Hellfire Club's Sebastian Shaw, but an extended retcon revealed that she was one of the first mutants recruited by Charles Xavier. She has been a member of the original X-Men teams, Excalibur, the Exiles, X-Force, and both versions of the X-Treme X-Men.

Sage appears in the television series The Gifted, portrayed by Hayley Lovitt.
