Ida Alison Browne (16 August 1900 – 21 October 1976) was an Australian geologist, petrologist and paleontologist at the University of Sydney.

While working as a demonstrator she was appointed a Delegate of the Commonwealth Government and Australian National Research Council to attend the Fourth Pacific Science Congress in Canada.

[5][9] Brown was promoted to full lecturer in 1940, and in 1941 published a paper on the fossiliferous Silurian and Devonian sequences of the Yass district with Germaine Joplin.

She attempted to work with colleague, Dorothy Hill from the University of Queensland to publish internationally, but mainly focused on Australian publications and her teaching responsibilities.

Ida Browne dedicated her life to teaching and providing adequate resources for the geologists and palaeontologists of the future.

She generously donated books to build the geological libraries at the University of Wollongong and the Australian Museum,[3] taught and mentored young women and promoted palaeontology.
