In their career, the British rock band Led Zeppelin recorded many songs that consisted, in whole or part, of pre-existing songs, melodies, or lyrics. They sometimes credited those sources; sometimes not. The band has been sued a number of times over attribution, some cases having concluded with others being awarded writing credit for the song in question. This is a partial list of songs that contributed to or inspired Led Zeppelin songs or covers. It includes non-controversial ones the band attributed to other writers from the outset.
