Bill Fontana (born in Cleveland, Ohio, April 25, 1947) is known internationally for his pioneering experiments in sound art.

Fontana attended New School for Social Research in New York and studied both music and philosophy. He traveled to Australia, and also stayed in Japan and Germany composing. Fontana began writing sound sculptures in 1976. In a career spanning 30 years, Fontana’s sound sculptures use the urban environment as a living source of musical information, all with the potential to conjure up visual imagery in the mind of the listener. He has made works all over the world and has presented his sound sculptures extensively, including at the Venice Biennale (1999), the Museo Reina Sofia, Madrid (1995), The Whitney Museum of American Art, New York (1991) and Tate Modern, London (2006), and Madison Square Park, New York (2007). Some of his more famous works include Distant Trains, Satellite Ear Bridge Cologne-San Francisco, Journey Through My Sound Sculptures, The Sound of an Unblown Flute, and Panoramic Echoes.
