Pendergrass, known for smash love ballads such as "Turn Off the Lights" and "Love TKO," died after a long illness, according to Lisa Barbaris, who described herself as a close friend and his last publicist.
He died at a hospital in Philadelphia, Pennsylvania, where he was born.
His family did not reveal details about his illness, but said it was related to complications from a 1982 car accident, Barbaris said.
"His beloved family surrounded him. The world has lost one of its greatest voices and performers," a statement from Barbaris said.
