"The Adventures of Greggery Peccary" is a piece by Frank Zappa. It originally released as Greggery Peccary on the album Studio Tan in 1978. A slightly different version was also included on the 1977 Läther album but this remained officially unreleased until 1996.

An instrumental version appears on the Wazoo CD featuring the original Wazoo ensemble and debuted at the Hollywood Bowl on September 10, 1972. On that CD it is in 4 movements totalling 33.05 minutes. The song is an epic lasting nearly 21 minutes, mocking the rock opera style and reprising the extended story format used in "Billy the Mountain" and, to some extent, the lengthy adventures outlined in the "Don't Eat the Yellow Snow Suite".

The piece required a large number of personnel to record, and received its basic tracking during The Grand Wazoo and Waka/Jawaka sessions in mid-1972. The piece remained unfinished at the time of release of those two LPs (later that year). Zappa would return to the recording on and off until its completion during the recording sessions for One Size Fits All in 1974. The long interludes of avant-garde classical arrangement that are prevalent in the track made for a much more sophisticated sound than "Billy the Mountain". Nonetheless, Zappa's use of absurdist humor and political commentary remains prevalent in this piece.
