Olga Mesmer is a superpowered fictional character in a pulp magazine's comic strip published from 1937 to 1938.

The first story, "The Astounding Adventures of Olga Mesmer, the Girl with the X-Ray Eyes", and subsequent installments are by an unidentified writer. Art for the strip, created at a comics studio run by Adolphe Barreaux, is credited to Watt Dell, who sometimes signed his illustrations for the magazine as Watt Dell Lovett, and may be a pseudonym; as well, some of the Mesmer strips are signed "Stone".

More generally, writes historian Peter Coogan, she is considered a precursor: References Further reading The Spectacular Sisterhood of Superwomen: Awesome Female Characters from Comic Book History by Hope Nicholson, Quirk Books (2017) 1937 comics debuts 1938 comics endings Mesmer, Olga Comics characters introduced in 1937 Mesmer, Olga Mesmer, Olga Mesmer, Olga Fiction set on Venus Comics about women Mesmer, Olga American comic strips Fiction about X-ray vision Superhero comic strips Comic strip superheroes Characters in pulp fiction
