Wintter Haynes Watts (1884–1962) was an American composer of art songs. Watts was born in Cincinnati, and his early studies were in painting, architecture, voice, and organ. He later studied at The Academy of Musical Art in New York and in Florence, Italy. He won the Morris Loeb Prize in 1919 for his symphony Young Blood and the Prix de Rome in 1923. He returned to Italy a few years later and stayed until 1931, when he returned to the United States. After 1931 he fell into obscurity.
