**Common Lisp**, commonly abbreviated **CL**, is a dialect of the Lisp programming language, standardised by ANSI X3.226-1994. Developed as a common successor to Maclisp and Lisp Machine Lisp, it is not an implementation but a language specification.

Several implementations of the Common Lisp standard are available, including commercial products and open source software: Steel Bank Common Lisp (SBCL), forked from the earlier CMU Common Lisp (CMUCL), is the most actively maintained open source implementation. CLISP was also a common choice in the past and is used by some Lisp books such as *Land of Lisp* (2010) for their code examples, but as of 2022 development has slowed to a crawl. LispWorks is the commonly used commercial alternative to SBCL and offers advanced GUI options, but is quite expensive and may not be worth it if a developer mainly wants to program non-GUI applications.

Common Lisp is a general-purpose programming language, in contrast to Lisp variants such as Emacs Lisp and AutoLISP which are embedded extension languages in particular products. Unlike many earlier Lisps, Common Lisp (like Scheme) uses lexical variable scope.

A "*" (SBCL), ">" (CLISP), or "CL-USER> " prompt seen in front of some examples shows that the code was run in a Lisp read-eval-print loop, or REPL, running interactively in an environment such as SLIME.
