John Bernard Munns, born in 1869 in Birmingham, England, was a portrait and landscape painter.

Munns belonged to a dynasty of Birmingham artists, being the son of Henry Turner Munns (1832-1898), a painter of portraits, landscapes and light-hearted genre, and the father of Una Munns (b.1900), who painted portraits and (in the true Birmingham tradition) made jewellery. John Bernard studied at the Birmingham School of Art and exhibited for many years with the Royal Birmingham Society of Artists, becoming an Associate in 1917 and a Member in 1923. He also supported the Royal Academy (1916-1927), the Royal Society of Portrait Painters and the Royal Institute of Oil Painters. His address was 40 St. James's Road, Edgbaston, and he died on 12 January 1942.
