"Host" is a song by British indie rock band The Crocketts. Credited to Davey MacManus and The Crocketts and produced by Charlie Francis, "Host" was featured on the band's 2000 second album The Great Brain Robbery, and released as its first single on 3 April 2000.

Writer and vocalist Davey MacManus has provided the following explanation of the song's meaning:

In their review of The Great Brain Robbery, magazine Welsh Bands Weekly described "Host" as an "addictive" song, claiming that it "sticks around inside your head for days ... and the pretty guitar sound is just so addictive".Kerrang! awarded the single four out of five Ks in their review, describing the song as "a slightly melancholy number ... a timely reminder that life can be amazing, even when it hurts".

The music video for "Host" was directed by Ralph Brown and produced by Mark Williams, both of whom also perform in the video. The video was filmed in Brighton on the request of Williams, including a number of "rich and red" theatre interiors on the West Pier. Williams describes the theme of the video as "a ghost story", and says that the inspiration came from listening to the lyrics of the song.
