'''XLISP''' is a family of [[Lisp (programming language)|Lisp]] implementations written by [[David Betz]] and first released in 1983.<ref>{{cite newsgroup|newsgroup=net.lang

The first version was a Lisp with [[object-oriented programming|object-oriented]] extensions for computers with limited power. The second version (XLISP 2.0) moved toward [[Common Lisp]], but was by no means a complete implementation. After a long period of inactivity, the author released a new version based on [[XSCHEME]], his Scheme implementation. The most current version follows the [[Scheme (programming language)|Scheme]] R3RS standard.{{fact|date=January 2016}}

==Derivatives==
* [[AutoLISP]], a programming and scripting language for [[AutoCAD]], is based on a very old version of XLISP.
* [[XLISP-PLUS]] is a derivative of XLISP 2.0 that continues to add [[Common Lisp]] features. [[Winterp]] is a derivative of XLISP-PLUS.
* [[XLISP-STAT]] is an implementation of [[Lisp-Stat]], an environment for dynamic graphics and statistics with objects.
* [[Nyquist (programming language)|Nyquist]] is an extension of XLISP for sound synthesis.
* [[ANIMAL (image processing)|ANIMAL]] (AN IMage ALgebra) is an image manipulation environment created by Carla Maria Modena and Roberto Brunelli.
* A 1989 entry to the [[IOCCC]] identifies itself as "XLISP 4.0".
