Trina Robbins (born 1938) is an American comics artist and writer. She was an early and influential participant in the underground comix movement, and one of the few female artists in underground comix when she started.
Robbins became an active member of science fiction fandom in the 1950s, and her illustrations appeared in science fiction fanzines such as the Hugo-nominated Habakkuk.
Robbins' first comics were printed in the East Village Other. In 1970 she left New York for San Francisco, where she worked at the feminist underground newspaper It Ain't Me, Babe. She subsequently established the first all-woman comic book titled It Ain't Me, Babe Comix. She became increasingly involved in creating outlets for and promoting female comics artists, through projects such as the comics anthology Wimmen's Comix. She was also the penciller on Wonder Woman for a time in the 1980s.
She also worked on an adaptation of Sax Rohmer's Dope for Eclipse Comics and GoGirl with artist Anne Timmons for Image Comics.
Trina designed Vampirella's costume for Forrest Ackerman and Jim Warren.
She is the first of the three "Ladies of the Canyon" in Joni Mitchell's classic song from the album of the same name.
Trina Robbins won a Special Achievement Award from the San Diego Comic Con in 1989 for her work on Strip AIDS U.S.A., a benefit book that she co-edited with Bill Sienkiewicz and Robert Triptow.
