John Francis Anthony “Jaco” Pastorius III (/ˈdʒɑːkoʊ pæˈstɔːriəs/; December 1, 1951 – September 21, 1987) was an American jazz bassist, composer and producer. He recorded albums as a solo artist and band leader and was a member of Weather Report from 1976 to 1981. He also collaborated with other artists, most notably Pat Metheny and Joni Mitchell. His bass playing employed funk, lyrical solos, bass chords, and innovative harmonics. As of 2017 he was the only electric bassist of seven bassists inducted into the DownBeat Jazz Hall of Fame, and he has been lauded as the best electric bassists of all time.

Pastorius suffered from drug addiction and mental health issues and, despite his widespread acclaim, over the latter part of his life he had problems holding down jobs due to his unreliability. In frequent financial difficulties, he was often homeless in the mid-1980s. He died in 1987 as a result of injuries sustained in a beating outside a South Florida after-hours nightclub.

Since his death in 1987, his work has continued to be widely influential. He was elected to the DownBeat Hall of Fame in 1988 and was the subject of the 2014 documentary film Jaco.
