Marta Hegemann (14 February 1894 – 28 January 1970) was a German artist associated with the Dada movement and with the Cologne Progressives.

In 1919, Hegemann was involved with developing a Cologne Dada group and its offshoot Stupid with Anton and her friend Angelika Hoerle.

[1] By the 1920s, Hegemann had become one of the most respected avant-garde artists in Cologne and her work was exhibited widely.

Her paintings featured surreal compositions executed in a style that combined elements of Dadaism, Constructivism, and New Objectivity.

One image shows Hegemann with several of her iconic motifs (birds, a heart) painted on one side of her face.
