Ms. Marvel is the name of several fictional superheroes appearing in comic books published by Marvel Comics. The character was originally conceived as a female counterpart to Captain Marvel. Like Captain Marvel, most of the bearers of the Ms. Marvel title gain their powers through Kree technology or genetics. Marvel has published three ongoing comic series titled Ms. Marvel, with the first two starring Carol Danvers, and the third starring Kamala Khan.

Carol Danvers is a fictional character appearing in American comic books published by Marvel Comics. Created by writer Roy Thomas and designed by artist Gene Colan, Major Carol Danvers first appeared as a member of the United States Air Force in Marvel Super-Heroes #13 (March 1968) and debuted as the first incarnation of Ms. Marvel in Ms. Marvel #1 (January 1977) after a fusion of alien Kree and human genes gives her superhuman powers, which occurred in Captain Marvel #18 (November 1969).
