Mervyn Wall (1908–1997) was an Irish writer who was born in Dublin. Wall attended Belvedere College and worked as a civil servant 1934–48, for Radio Éireann from 1948–57, and as Secretary of the Arts Council for 1957–75. His wife, Frances Feehan, was a theatre and music critic.
Wall published novels, short stories and plays, and wrote for a short-lived literary magazine, Ireland Today.
Wall wrote two humorous fantasy novels, The Unfortunate Fursey and The Return of Fursey, about the misadventures of a monk in Dark Ages Ireland. The Fursey novels have been highly praised in North America. E. F. Bleiler in The Guide to Supernatural Fiction described The Unfortunate Fursey as "a landmark book in the history of fantasy". Darrell Schweitzer described Wall as "one of the finest comic fantasists ever, but also one of the most neglected."  Parke Godwin described both Fursey novels as "pure gold".
