Wonder Woman is a fictional DC Comics superheroine. Co-created by William Moulton Marston with his wife Elizabeth (Sadie) Holloway Marston, Wonder Woman first appeared in All Star Comics #8 (Dec. 1941). She is one of the first female superheroes and arguably the most famous.

In most adaptations, Wonder Woman is Princess Diana of the Amazon warrior tribe of Greek mythology. "Diana" is the Roman name for the Greek goddess on whom this character is based; "Artemis" is her Greek name. The Amazon ambassador to the larger world, she possesses several superhuman abilities and gifts from the Greek gods including the Lasso of Truth created from the Golden Girdle of Gaea and indestructible silver bracelets formed from the shield Aegis. For several years she was described, in the splash page of each story, as being "beautiful as Aphrodite, wise as Athena, swifter than Mercury and stronger than Hercules." She is also a member of the Justice League.

Marston designed the character Wonder Woman as a distinctly feminist character and many subsequent writers, especially those of the 1970s and afterward, have written her as such.
