Dame Elizabeth Blackadder, (born 24 September 1931) is a Scottish painter and printmaker. She is the first woman to be elected to both the Royal Scottish Academy and the Royal Academy.
In 1962 she began teaching at Edinburgh College of Art where she continued until her retirement in 1986. Blackadder worked in a variety of media such as oil paints, watercolour, drawing and printmaking. In her still life paintings and drawings, she considers space between objects carefully.
She also paints portraits and landscapes but her later work contains mainly her cats and flowers with extreme detail. Her work can be seen at the Tate Gallery, the Scottish National Gallery of Modern Art, and the Museum of Modern Art in New York, and has appeared on a series of Royal Mail stamps.
