Mary Jane Watson is a fictional supporting character appearing in comic books published by Marvel Comics. The character primarily appears in the Spider-Man titles as the best friend, love interest, and in some continuities wife (as Mary Jane Watson-Parker) of the title character (specifically, his alter-ego, Peter Parker). Created by writer Stan Lee and artist John Romita, Sr., after a few partial appearances and references, she finally first fully appeared in The Amazing Spider-Man #42 (November 1966).

She is depicted as a gorgeous, green-eyed redhead and has been the primary romantic interest of Spider-Man’s alter ego Peter Parker for the last twenty years, although initially competing against others for his affection, most prominently with Gwen Stacy and the Black Cat. Mary Jane's relatively unknown early life was eventually explored in Amazing Spider-Man' #259

Today, Mary Jane is considered an important part of the Spider-Man series and has been featured in most other media adaptations of the character. She has even been the main character of some comics and novels aimed at young female readers. Actress Kirsten Dunst portrayed her in the recent film series.
