Clozure CL (CCL) is a Common Lisp implementation.

Quoting the wilkipedia page:

Clozure CL (CCL) is a Common Lisp implementation. It implements the full ANSI Common Lisp standard with several extensions (CLOS MOP, threads, CLOS conditions, CLOS streams, etc.) It contains a command line development environment, an experimental integrated development environment (IDE) for Mac OS X using the Hemlock editor, and can also be used with SLIME (a Common Lisp development environment for GNU Emacs).

The official page is in here.
