'''Lisp Machine Lisp''' is a [[programming language]], a [[Dialect (computing)|dialect]] of the language [[Lisp (programming language)|Lisp]]. A direct descendant of [[Maclisp]], it was initially developed in the mid to late 1970s as the [[system programming]] language for the [[Massachusetts Institute of Technology]] (MIT) [[Lisp machine]]s. Lisp Machine Lisp was also the Lisp dialect with the most influence on the design of [[Common Lisp]].

Lisp Machine Lisp branched into three dialects. [[Symbolics]] named their variant ZetaLisp. [[Lisp Machines]], Inc. and later [[Texas Instruments]] (with the [[TI Explorer]]) would share a common code base, but their dialect of Lisp Machine Lisp would differ from the version maintained at the [[MIT Computer Science and Artificial Intelligence Laboratory|MIT AI Lab]] by [[Richard Stallman]] and others.
