Baron von Tollbooth & the Chrome Nun is a collaborative studio album by Jefferson Airplane members Paul Kantner, Grace Slick, and David Freiberg, released in May 1973.

All of the trio's then-fellow Jefferson Airplane members, John Barbata, Jack Casady, Papa John Creach, and Jorma Kaukonen, are featured on the album.

Also appearing are David Crosby, Jerry Garcia, Mickey Hart, The Pointer Sisters, and Craig Chaquico (the future lead guitarist of Jefferson Starship).

"Your Mind Has Left Your Body" was the final studio track to feature Paul Kantner, Grace Slick, Jorma Kaukonen and Jack Casady until the 1989 Jefferson Airplane reunion album.

The album cover was illustrated by Drew Struzan under the direction of Ernie Cefalu.
