Allegro Common Lisp is a programming language with an integrated development environment (IDE), developed by Franz Inc. It is a dialect of the language Lisp, a commercial software implementation of the language Common Lisp. Allegro CL provides the full American National Standards Institute (ANSI) Common Lisp standard with many extensions, including threads, CLOS streams, CLOS MOP, Unicode, SSL streams, implementations of various Internet protocols, OpenGL interface.{{cite web |url=http://www.franz.com/support/documentation/current/doc/contents.htm |title=Allegro CL 10.0 documentation |website=Franz Inc. |date=January 21, 2010 |access-date=July 19, 2013}}{{cite web |url=https://common-lisp.net/~dlw/LispSurvey.html |title=Common Lisp Implementations: A survey |website=Common-Lisp.net |archive-url=https://web.archive.org/web/20180622083812/https://common-lisp.net/~dlw/LispSurvey.html |archive-date=June 22, 2018 |url-status=dead |df=mdy-all }} The first version of Allegro Common Lisp was finished at the end of 1986,{{cite web |url=http://franz.com/about/company.history.lhtml |title=History of Franz Inc. |author= |website=Franz Inc. |date= |access-date=2018-12-23}} originally called Extended Common Lisp.{{cite magazine |date=1986-08-04 |title=Extended Common Lisp |magazine=Computerworld |publisher=IDG Communications |page=7 }} Allegro CL is available for many operating systems including Microsoft Windows (32/64-bit), and many Unix and Unix-like, 32-bit or 64-bit, including macOS (Intel, 32/64-bit), Linux (32/64-bit), FreeBSD (32-bit), Solaris (x64, SPARC; 32/64-bit), UNICOS, and UTS. Internationalization and localization support is based on Unicode. It supports various external text encodings and provides string and character types based on Universal Coded Character Set 2 (UCS-2). Allegro CL can be used with and without its integrated development environment (IDE), which is available for Windows, Linux, and on macOS in version 8.2. The IDE (written in Allegro CL) includes development tools including an editor and an interface designer. Allegro CL can be used to deliver applications.

Allegro CL is available as freeware, a Free Express Edition (with some limits like a constrained heap space) for non-commercial use.{{cite web |url=http://www.franz.com/downloads/clp/survey |title=Allegro CL 10.0 Free Express Edition Downloads |website=Franz Inc. |access-date=2013-07-19}} Customers can get access to much of the source code of Allegro CL.

Allegro CL includes an implementation of Prolog{{cite web |url=http://www.franz.com/support/documentation/current/doc/prolog.html |title=Allegro Prolog (Allegro CL version 10.0 documentation) |website=Franz Inc. }} and an object caching database called AllegroCache.{{cite web |url=http://franz.com/products/allegrocache/ |title=AllegroCache |author= |date=2018 |website=Franz Inc. |access-date=2018-12-21}}{{cite web |url=http://www.defmacro.org/ramblings/relational.html |title=Databases: A New Frontier |last=Akhmechet |first=Slava |website=defmacro |url-status=dead |access-date=2018-12-23 |archive-url=https://web.archive.org/web/20161005024518/http://www.defmacro.org/ramblings/relational.html |archive-date=October 5, 2016 |df=mdy-all }}
