Weather Report was an American jazz fusion band of the 1970s and early 1980s. The band was co-led by the Austrian-born keyboard player Joe Zawinul and the American saxophonist Wayne Shorter (and, initially, by Czech bass player Miroslav Vitouš). Other prominent members at various points in the band's lifespan included Jaco Pastorius, Peter Erskine, Alex Acuña, Alphonso Johnson, Victor Bailey, Airto Moreira and Chester Thompson.

Alongside Miles Davis's electric bands, The Mahavishnu Orchestra, Return to Forever, and Headhunters, Weather Report is considered to be one of the earliest pre-eminent jazz fusion bands. As a continuous working unit, Weather Report outlasted all of its contemporaries despite (or perhaps because of) frequent changes of personnel, with a career lasting sixteen years between 1970 and 1986.
