Nancy Tyson Burbidge AM (5 August 1912 – 4 March 1977) was an Australian systemic botanist, conservationist and herbarium curator.

[1][5] Nancy Burbidge was educated at Katanning (Kobeelya) Church of England Girls' School, founded by her mother in 1917.

She completed her BSc in 1937, and afterwards received a prize to travel to England, where she spent 18 months at the Royal Botanic Gardens Kew.

[5][4] In 1943, Burbidge was appointed assistant agronomist at the Waite Agricultural Research Institute in Adelaide, where she started working on native pasture species for arid and semi-arid South Australia.

After resigning her position as curator of the herbarium she went on to be heavily involved in the development of the Flora of Australia series, directing the project from 1973 to 1977.

[8] In addition to her books, she also wrote over 50 papers on phytogeography, ecology, botanical history and Australian plant genera.

She was a founding member of the National Parks Association of the Australian Capital Territory in 1960, and twice served as its president.

[9] Burbidge's contributions are commemorated by an altar-frontal, showing banksias and honey-eaters, in St Michael's Anglican Church, Mount Pleasant, Western Australia,[8] and by the Nancy T. Burbidge Memorial, an amphitheatre in the Australian National Botanic Gardens in Canberra.

[12] The "Nancy T. Burbidge Medal" has been presented annually since 2001 by the Australasian Systematic Botany Society, for longstanding and significant contributions to taxonomic and systematic botanical work in Australasia, and the recipient delivers the Nancy T. Burbidge Memorial Lecture at the Society's annual conference.
