"Knee Deep" is a song recorded by American country music group Zac Brown Band with Jimmy Buffett.

Wyatt Durrette, the co-writer of "Knee Deep", told the website Taste of Country that he has been a longtime fan of Jimmy Buffett and that he wanted to write a beach-themed song.

[2] Steve Morse of the Boston Globe called "Knee Deep" "festive" and a "highlight" of the album.

[3] Country Weekly reviewer Jessica Phillips said that the song was "happy-go-lucky" but "sounds like a derivation of the band's own hit "Toes".

[4] Eric R. Danton of the Hartford Courant called it "exactly the kind of song you'd expect to hear Jimmy Buffett sing, but with more mandolin".
