25th Anniversary Box Set is a 1993 limited edition box set by Jethro Tull. It includes some of the band's best-known compositions from 1969 to 1992, many of them previously unavailable in the versions presented here. It was the second Jethro Tull box-set in five years, the first being the 3CD/ 5LP/ 3Cassette 20 Years of Jethro Tull.
The CDs are housed in a mock cigar-box, along with a booklet featuring extensive notes and photographs, sealed with a label bearing an image of Ian Anderson.
