Elizabeth Ann Dewar Churcher AO (née Cameron; 11 January 1931 – 31 March 2015) was an Australian arts administrator, best known as director of the National Gallery of Australia from 1990 to 1997. She was also a painter in her own right earlier in her life.

Elizabeth Cameron was born on 11 January 1931 in Brisbane. From age 7 to 15 she attended Somerville House school, paid for by her grandmother. There she was taught art by Patricia Prentice. She left school after grade 10 because her father did not think she needed a higher education.

In 1942 as an 11-year-old, Churcher saw Blandford Fletcher's Evicted at the Queensland Art Gallery, which inspired her to become an artist. After leaving school, she studied under artist Caroline Barker.

Churcher won a Royal Queensland Art Society travelling scholarship to Europe and attended the Royal College of Art in London. She received a Master of Arts from the Courtauld Institute of Art, University of London, in 1977.

In the years preceding the formation of the Queensland Branch of the Contemporary Art Society, Betty and her husband Roy Churcher involved a new group of people who were interested in contemporary art (in particular modernism) in Brisbane. (Roy was a key instigator of the establishment of the society, and became one of two inaugural vice-presidents when it was established in 1961.)

Between 1972 and 1975, Churcher was art critic for The Australian newspaper.

She became Dean of School of Art and Design in 1982, and taught Art History at the progressive Phillip Institute of Technology (now RMIT University) until 1987, when she was appointed director of the Art Gallery of Western Australia. She left in 1990 after disagreements with Robert Holmes à Court about the gallery's acquisition of a Pierre Bonnard painting.

She was then appointed director of the Australian National Gallery. She hosted several television shows in the 1990s and authored several books, including The Art of War about war artists.^{[citation needed]}
