Eilís Dillon (7 March 1920 – 19 July 1994) was an Irish author of 50 books. Her work has been translated into 14 languages.
Educated by the Ursuline nuns in Sligo, she worked briefly in the hotel and catering trade. In 1940 she married Cormac Ó Cuilleanáin, an academic from University College Cork and 17 years her senior. They had at least 3 children, including the Irish poet and Trinity College Dublin professor Eiléan Ní Chuilleanáin and her brother, Cormac Ó Cuilleanáin, also a Trinity professor, who writes novels as Cormac Millar.
She started to produce children's books, in Irish, and later in English in the 1940s, including a string of successful teenage novels, some of which (The Lost Island, The Island of Horses) were still in print 50 years later.
In the 1960s she moved to Rome. Following her husband's death in 1970 she published her most successful historical novel, Across the Bitter Sea (1973), and in 1974 married the American-based critic and professor Vivian Mercier.
