Eva Philbin (4 January 1914 – 24 June 2005) was an Irish chemist who became the first woman president of the Institute of Chemistry of Ireland.

In 1939, due to World War II, she changed paths to industrial chemistry and became chief chemist at the farm chemical manufacturer Hygeia Ltd in Galway.

During this time, she was also chief chemist at Cold Chon Ltd, a manufacturer of bituminous binders and road surfacing materials.

She earned her Ph.D. in 1956, then had a brief stint as a visiting fellow at the Eidgenossische Polytechnikum Zurich with Vladimir Prelog, working on flavonoid stereochemistry.

[2][8] She continued to work on flavonoid stereochemistry and the compounds' role as potential anti-cancer agents through collaborations with researchers including Hugh Ryan and Elias James Corey.

[2][15] Her son Liam's disability was the impetus for her work with the National Association for the Mentally Handicapped of Ireland, which continued through her entire life.
