Sylvester Mubayi (born 1942) is a Zimbabwean sculptor.
A native of the Chiota Reserve near Marondera, Mubayi worked as a tobacco grader after leaving school; in 1966 he moved to Salisbury to look for work at the Chibuku Breweries. He joined the Tengenenge Sculpture Community in 1967 as one of its first members, and later worked at the Workshop School founded by Frank McEwen in Vukutu. He has also served as an artist in residence at the Chapungu Sculpture Park. Mubayi currently lives and works in Chitungwiza; his sculptures are inspired by stories of spirits and the supernatural. The National Gallery of Zimbabwe held a retrospective of his life’s work in August 2008 to much acclaim.
