Elizabeth Alice Flint OBE (26 May 1909 – 7 December 2011) was a New Zealand botanist who specialised in freshwater algae.
Flint then undertook doctoral studies at Queen Mary College, London, under the supervision of Felix Eugen Fritsch, investigating the changes in distribution of algae in a reservoir at Barn Elms, near Hammersmith.
During World War II, Flint worked in London at the Metropolitan Water Board laboratory, and then, between 1943 and 1945, did operational research for the Royal Air Force.
She then worked at the Shirley Institute of the British Cotton Industry Research Association, before returning to New Zealand in 1947 to lecture in botany at Victoria University College in Wellington.
