Sonia Delaunay (born 1885) was a Ukrainian painter.

Together with her husband Robert Delaunay, they developed their own concept of abstraction as a universal language.

Sonia Delaunay went even further, developing this concept in a variety of media. The '30s saw the blossoming of a refined abstraction, characteristic of the international style.

After the war, Sonia Delaunay's painting underwent a profound renewal that culminated, in the late 1960s, in an intensely poetic abstract art. Her formal and technical creativity was expressed in monumental works in painting, mosaic, carpet and tapestry.
