'''Maclisp''' (or '''MACLISP''', sometimes styled '''MacLisp''' or '''MacLISP''') is a [[programming language]], a [[Dialect (computing)|dialect]] of the language [[Lisp (programming language)|Lisp]]. It originated at the [[Massachusetts Institute of Technology]]'s (MIT) [[Project MAC]]<ref name="hackers">{{cite book |last=Levy |first=Steven |author-link=Steven Levy |title=[[Hackers: Heroes of the Computer Revolution]] |publisher=Doubleday |year=1984 |isbn=0-385-19195-2}}</ref> (from which it derived its prefix) in the late 1960s and was based on Lisp 1.5.<ref>{{cite report |title=Project MAC Progress Report IV: July 1966 to July 1967 |date=n.d. |page=19 |quote=The higher-level language used for most of the vision laboratory program is the PDP-6 LISP System. This system is based chiefly on the LISP 1.5 programming language, but has been extensively modified in a number of ways. These include many new functions and services, including facilities for linking with programs written in other languages. |url=http://www.dtic.mil/dtic/tr/fulltext/u2/681342.pdf |url-status=dead |archive-url=https://web.archive.org/web/20160308100743/http://www.dtic.mil/dtic/tr/fulltext/u2/681342.pdf |archive-date=March 8, 2016}}</ref> [[Richard Greenblatt (programmer)|Richard Greenblatt]] was the main developer of the original codebase for the [[PDP-6]];<ref name="hackers" /> Jon L.

The name ''Maclisp'' began being used in the early 1970s to distinguish it from other [[Fork (software development)|fork]]s of PDP-6 Lisp, notably [[BBN Lisp]].
