mod_lisp is an extension module for the Apache HTTP Server. It enables Apache to interface with application servers{{cite web|url=http://www.fractalconcept.com/asp/y441/sdataQ1n29oWG$ycvDM==/sdataQuvY9x3g$ecX|title=mod_lisp home page}} written in Common Lisp, making it possible to dynamically generate web pages and provide web applications with Common Lisp programs.{{cite web

Unlike other {{mono|mod_*}} projects, such as mod_perl and mod_python, mod_lisp does not embed a Common Lisp interpreter in Apache. In concept it is closer to FastCGI, handling requests by serializing them into a textual representation and sending that over a socket to a persistent Common Lisp program, and then sending the Common Lisp system's response to a client.{{cite web
