James Robert Haslip (born December 31, 1951) is an American bass guitarist who was a founding member of the jazz fusion group the Yellowjackets, which he left in 2012. He was also an early user of the five-string electric bass. Born in the Bronx to Puerto Rican immigrants, Spanish was Haslip’s first language and he learned to speak English in kindergarten. His father, James Joseph (Jaime) Haslip (1915–1999) served in the United States Customs Service, beginning as a Merchant Marine until moving to patrolman and eventually deputy commissioner, marrying Jimmy’s mother Virginia (Viera) Haslip (1912–2009) in 1937.
