Frank J. Hugh O'Donnell (4 April 1894 – 4 November 1976) was an Irish critic, playwright and politician.
His first play The Dawn Mist (1919) follows a Galway family, the Egans, who lose two brothers and an uncle in the 1916 Easter Rising.
In 1943 he became a member of Seanad Éireann on the Industrial and Commercial Panel where he promoted Irish arts and culture.
A collection of O'Donnell's papers and manuscripts dating from 1911 to 1974 kept at the University of Delaware Library, is open for research.
He bore almost the same name as a contemporary politician, Frank Hugh O'Donnell, also from County Galway.
