"Castaway" is a song recorded by American country music group Zac Brown Band. It was released as the sixth single from the band's fourth studio album, Jekyll + Hyde, on April 25, 2016. The song was written by Zac Brown, Coy Bowles, John Driskell Hopkins, Wyatt Durrette and Niko Moon.

The song is an upbeat, reggae-influenced tune^[1] about a man who wants to relax on a beach as a "castaway".

An uncredited review from Taste of Country was positive, saying that "The textured vocals are much more compelling than anything from the arrangement, although it’s pretty tough not to enjoy the groove the Zac Brown Band band are laying down in 'Castaway.' It’s actually been some time since ZBB released an island-flavored single, and the timing couldn’t be better for this brand of country music."^[1]
