William Earl “Bootsy” Collins (born October 26, 1951) is an American musician, singer and songwriter.

Rising to prominence with James Brown in the early 1970s, and later with Parliament-Funkadelic, Collins’s driving bass guitar and humorous vocals established him as one of the leading names in funk. He is a member of the Rock and Roll Hall of Fame, inducted in 1997 with 15 other members of Parliament-Funkadelic. Collins was born in Cincinnati, Ohio, United States, on October 26, 1951. He said that his mother named him “Bootsy”. “I asked her why,” he explained to a journalist, “and she just said, ‘Because you looked like a Bootsy.’ I left it at that.”

His brother Phelps “Catfish” Collins (1943–2010) was also a musician. He and Bootsy were once part of James Brown’s backing band, The Pacemakers.
