Spice Lisp (Scientific Personal Integrated Computing Environment) is a programming language, a dialect of Lisp. Its implementation, originally written by Carnegie Mellon University's (CMU) Spice Lisp Group, targeted the microcode of the 16-bit workstation PERQ, and its operating system Accent.{{cite book

It would later be popular on other workstations.

Spice Lisp evolved into an implementation of Common Lisp, and was renamed CMU Common Lisp (CMUCL).
