Walter Nugent Monck (1878–1958) was an English theatre director and founder of Maddermarket Theatre, Norwich. He was born in Welshampton, Shropshire, the son of George Gustavus Monck (1849–1920), vicar of Welshampton who later worked as a priest in Liverpool. The son was educated there and at the Royal Academy of Music. In 1895, he abandoned his study of the violin in favour of acting. After some years with a regional touring company, he premiered in London in Bjørnstjerne Bjørnson's Beyond Human Power at the Royalty Theatre in 1901.
