German painter who was closely affiliated with the artists' group Der Blaue Reiter (Blaue Reiter, Der) (“The Blue Rider”).

Münter studied the piano throughout her youth. In 1902 she entered the Phalanx School of art in Munich, Germany, where within a year she began to attend classes in still life and landscape taught by the painter Wassily Kandinsky (Kandinsky, Wassily), who was the director of the school. The two became involved romantically, and they traveled widely together before settling again in Germany, where they divided their time between Munich and the village of Murnau in the Bavarian Alps.

Münter was one of the founders in 1909 of the avant-garde artists' group Neue Künstlervereinigung (“New Artists' Association”). In 1911 she joined Kandinsky in leaving the group to form the rival association, Der Blaue Reiter. Münter exhibited paintings at the Blaue Reiter exhibitions of 1911 and 1912. While sharing the group's characteristic intensity of colour and expressiveness of line, her still lifes, figures, and landscapes remained uniquely representational rather than abstract. Her notable works include Portrait of a Young Woman (1909) and Red Cloud (1911). Münter and Kandinsky ended their relationship about 1916. In her later work she used a more subdued palette and often painted portraits of women.
