Dame Elizabeth Blackadder (1931 — 2021) was a renowned Scottish painter. Well-known for her highly detailed still life paintings, the artist also produced portraits and landscapes working in a variety of media including oils, watercolour, drawing, and printmaking.

Blackadder was born and raised in Falkirk, leaving in 1949 to study at the Edinburgh College of Art. It was there that she met her husband, fellow artist and ACS member, John Houston.

Blackadder was the first woman to be elected to both the Royal Scottish Academy and the Royal Academy. In 1982, Blackadder was awarded an OBE for her contribution to art which was promoted to a DBE in 2003.

Her work is included in collections at the Tate Gallery, the Scottish National Gallery of Modern Art, and the Museum of Modern Art in New York.
