"Key West (Philosopher Pirate)" is a song written and performed by the American singer-songwriter Bob Dylan and released as the ninth track on his 2020 album Rough and Rowdy Ways. It is a mid-tempo, accordion-driven ballad that has been cited as a high point of the album by many critics.

It is the only song on the album to feature a traditional chorus and one of only two songs (the other being "I've Made Up My Mind to Give Myself to You") to feature backing vocals.
