Jeffrey Linton Osborne (born March 9, 1948) is an American funk and R&B musician, songwriter, lyricist, and former lead singer of the band, L.T.D.

Osborne was born in Providence, Rhode Island. He is the youngest of 12 children and is part of a musical family.

Osborne started his music career in 1970 with a band called Love Men Ltd., who would later become known as L.T.D. The band recorded hit singles such as "(Every Time I Turn Around) Back in Love Again", "Concentrate on You," "Love Ballad" and "Holding On (When Love Is Gone)". At first, Osborne was a drummer, sharing lead vocal duties with his brother Billy, but by 1978 he became the group's primary lead vocalist. He and Billy both left L.T.D. in late 1980 to start solo careers. His solo success includes five gold and platinum albums.
