Original Masters is a greatest hits album by Jethro Tull released under Chrysalis Records in 1985. It was the band's third such effort, the first two being M.U. – The Best of Jethro Tull and Repeat – The Best of Jethro Tull – Vol II. Although the compilation was released in 1985, it does not include material released after 1977. The first two compilations had material released exclusively up to 1977 and Original Masters covers much of that same material with a few extras. The CD's back insert, as well as the back cover of the LP's sleeve, mislabels the song "The Witch's Promise" as "Witches Promise".
