"Peaches en Regalia" is an instrumental jazz fusion composition by Frank Zappa. It was released on Zappa's album Hot Rats in 1969 and has been recorded many times since. It was also released as a single in 1970, with "Little Umbrellas" as the B-side. Zappa used the piece on many of his tours, often as either the opening or the encore of a show.

"Peaches en Regalia" has been included in the "underground" version of The Real Book, despite being compositionally more complicated than typical jam session tunes. Having a song included in the book has been described "the ultimate insider credential for a jazz composer".

The tune is used as instrumental background music on the BBC London radio programme presented by Danny Baker. It was also the theme tune for the early 1970s BBC2 show One Man's Week.

A cover of the piece recorded by Zappa Plays Zappa (including Zappa's son Dweezil and former Zappa alumni Steve Vai and Napoleon Murphy Brock) won a Grammy Award for Best Rock Instrumental Performance in February 2009.

Don Miguel Vilanova (aka Botafogo), an Argentine blues musician, had a band in the late 1980s, inspired by the blues and specifically Zappa's song "Peaches en Regalia", the name of which was translated literally into the Spanish as "Durazno de Gala".
