The Led Zeppelin bootleg recordings are a collection of audio and video recordings of musical performances by the English rock band Led Zeppelin which were never officially released by the band, or under other legal authority. The recordings consist of both live concert performances and outtakes from studio sessions conducted by the band. Many hundreds of Led Zeppelin bootlegs exist, and are widely collected by fans.

Led Zeppelin were, throughout the decade of the 1970s, one of the world's most frequently bootlegged performers, and to this day remain one of the most bootlegged artists in the history of rock music. In August 1999, the band topped the list of Britain's most bootlegged musicians with 384 bootleg titles, compiled by the Anti-Piracy Unit of British Phonographic Industry. This phenomenon was due partly to the popularity of the band, which has ensured a large and enthusiastic market for unauthorised recordings, and partly to the large size of the audiences who attended their performances, which made the effective detection of covert recording equipment at these concerts virtually impossible.

Led Zeppelin's manager, Peter Grant, sometimes took extraordinary measures to combat the practice of live bootleg recordings at Led Zeppelin concerts. He is reported to have personally visited record stores in London that were selling Led Zeppelin bootlegs and demanded all copies be handed over. He also monitored the crowd at Led Zeppelin concerts so as to locate anything which resembled bootleg recording equipment. At one concert at Vancouver in 1971 he saw what he thought was recording equipment on the floor of the venue and personally ensured that the equipment be destroyed, only to find out later that the equipment was a noise pollution unit being operated by city officials to test the volume of the concert. Similarly, at the Bath Festival in 1970, he personally threw a bucket of water over unauthorised recording equipment.

These efforts were not enough to prevent the release of a flood of Led Zeppelin bootlegs from the 1970s onwards. As is explained by Led Zeppelin archivist Dave Lewis:

Bootlegs and Led Zeppelin have been synonymous for over three decades. Despite manager Peter Grant's heavy-handedness when dealing with those he caught taping their shows, the band are the most bootlegged act of all time, outstripping even The Beatles, [Bob] Dylan, [Bruce] Springsteen and the [Rolling] Stones. Their final seven shows in the UK alone (five at Earl's Court and two at Knebworth), account for over 100 different releases between them. Just about every amateur recording of the band's live gigs has [been released]."

During the 1970s, bootleg labels such as Smilin' Ear, Kornyfone, Dragonfly, Trade Mark of Quality, Condor and Toasted released unofficial recordings of several Led Zeppelin shows on vinyl. The following table includes a sample of these recordings. Most of them derived from audience tapes, though a few (such as Destroyer) were sourced from soundboard recordings.

In the late 1980s, the number of available soundboard recordings of Led Zeppelin shows increased significantly as a result of original soundboard tapes being stolen during a burglary at the home of Led Zeppelin guitarist Jimmy Page and later copied for underground release. Also stolen were copies of several rare studio out-takes, which were released under titles such as Jennings Farm Blues (featuring run-throughs of an electric version of "Bron-Y-Aur Stomp" recorded in October 1969) and Studio Daze (including different studio mixes of "Since I've Been Loving You", "No Quarter" and "All My Love"). "Midnight Moonlight", a song later recorded by "The Firm", is also available through studio bootlegs.

The 1990s saw a multitude of Led Zeppelin bootlegs become available on the CD format, with limited-edition and higher quality releases being produced in Japan on labels such as Tarantura and Antrabata. The most significant 90s label TDOLZ (The Diagrams of Led Zeppelin) has covered most of the circulating concerts for that period releasing over 100 titles. In 1999, the BBC reported that the number of Led Zeppelin bootleg titles in circulation exceeded those of The Beatles.
