MIT/GNU Scheme is a programming language, a dialect and implementation of the language Scheme, which is a dialect of Lisp. It can produce native binary files for the x86 (IA-32, x86-64) processor architecture. It supports the R7RS-small standard.[3] It is free and open-source software released under v2 or later of the GNU General Public License (GPL).[4] It was first released by Guy Lewis Steele Jr. and Gerald Jay Sussman at the Massachusetts Institute of Technology in 1986,[5] as free software even before the Free Software Foundation, GNU, and the GPL existed.[6] It is now part of the GNU Project.[7]

It features a rich runtime software library, a powerful source code level debugger, a native code compiler and a built-in Emacs-like editor named Edwin.

The books Structure and Interpretation of Computer Programs and Structure and Interpretation of Classical Mechanics include software that can be run on MIT/GNU Scheme.
