Frank J. Hugh O'Donnell (4 April 1894 – 4 November 1976) was an Irishcritic, playwright and politician.
O'Donnell was born at Shop Street, Tuam, County Galway to John O'Donnell and his wife Delia (née Carr) but spent his childhood in Milltown, County Galway. O'Donnell was enrolled in Milltown National School in November 1902 aged eight and left in June 1909 aged fifteen. He and his brother Patrick O'Donnell worked in the family business in Tuam before moving to Dublin to work in the clothing industry. He was a published critic of music, literature and theatrical performances, and wrote a weekly letter in the Gael, a weekly paper. He was also a playwright, having some of his works staged at the Abbey Theatre.
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. The play became very popular, however; it was banned by the British authorise earning the title of "Ireland's most proclaimed [banned] play".
