Douglas Alan Yule is an American musician and singer, most notable for being a member of the Velvet Underground from 1968 to 1973, serving as the bassist, guitarist, keyboardist and occasional lead vocalist.

The Velvet Underground was an American rock band formed in New York City in 1964. It originally comprised singer and guitarist Lou Reed, Welsh multi-instrumentalist John Cale, guitarist Sterling Morrison, and drummer Angus MacLise. In 1965, MacLise was replaced by Moe Tucker, who played on most of the band's recordings. Though their integration of rock and the avant-garde resulted in little commercial success, they became one of the most influential bands in rock, underground, experimental, and alternative music. Their provocative subject matter, musical experiments, and nihilistic attitude was also instrumental in the development of punk rock, new wave and several other genres.
