William Anthony Colón Román (born April 28, 1950) is an American Salsa musician and social activist. He began his career as a trombonist but also sings, writes, produces and acts. Colón is considered a pioneer of Salsa music and a best-selling artist in the genre, having been a key figure in the nascent New York City scene associated with the legendary Fania Records. He is also noteworthy for having assumed the gangster image in his album covers before it was culturally popular. Since the 1980s he has at times been deeply involved in the politics of New York City.
