Amy Barrington (died 6 January 1942) was an Irish teacher and scientist who was closely associated with the practices and beliefs of eugenics. She published several papers on that subject as well as indexing a work on history. She also wrote an account of the family history of the Barringtons. Amy Barrington herself states in 'The Barrington family history' that she occupied herself in learning and travelling for 26 years before deciding to pursue her family's ancestral history. She was the youngest daughter of Edward Barrington of Fassaroe, Bray, County Wicklow, Ireland.
