Gambit, also called Gambit-C, is a programming language, a variant of the language family Lisp, and its variants named Scheme. The Gambit implementation consists of a Scheme interpreter, and a compiler which compiles Scheme into the language C, which makes it cross-platform software. It conforms to the standards R⁴RS, R⁵RS, and Institute of Electrical and Electronics Engineers (IEEE), and to several Scheme Requests for Implementations (SRFIs).{{cite web |url=http://dynamo.iro.umontreal.ca/~gambit/wiki/index.php/Documentation |title=Documentation |work=Gambit wiki |access-date=2010-03-06 |archive-date=2021-02-26 |archive-url=https://web.archive.org/web/20210226191750/http://dynamo.iro.umontreal.ca/~gambit/wiki/index.php/Documentation |url-status=dead }} Gambit was released first in 1988, and Gambit-C (Gambit with a C backend) was released first in 1994. They are free and open-source software released under a GNU Lesser General Public License (LGPL) 2.1, and Apache License 2.0.

By compiling to an intermediate representation, in this case portable C (as do Chicken, Bigloo and Cyclone), programs written in Gambit can be compiled for common popular operating systems such as Linux, macOS, other Unix-like systems, and Windows.
