"Misty Mountain Hop" is a song by English rock band Led Zeppelin that was released in 1971 by Atlantic Records.

[3] The most common interpretation of the song's title involves a reference to the Misty Mountains in J. R. R. Tolkien's The Hobbit.

The lyrics refer to the events of the 7 July 1968 "Legalise Pot Rally" in Hyde Park, London, in which police made arrests for marijuana possession.

[4] The lyrics reflect Plant's quest for a better society, a place and time when hangups are replaced with individual freedom and a life of mutual support and rapport.

A different version of this song is featured on the second disc of the remastered two CD deluxe edition of Led Zeppelin IV.
