MicroEMACS is a small, portable Emacs-like text editor originally written by Dave Conroy in 1985, and further developed by Daniel M. Lawrence (1958–2010{{cite web|url=http://le-trombone.livejournal.com/182656.html |title=Daniel M.

Earle Harris |access-date=January 11, 2012}}) and was maintained by him. MicroEMACS has been ported to many operating systems, including CP/M,{{cite web|url=http://www.commodore.ca/manuals/funet/cpm/editors/|title=ftp.funet.fi:/pub/cpm/editors/|website=www.commodore.ca|access-date=6 February 2018}} MS-DOS, Microsoft Windows, VMS, Atari ST, AmigaOS, OS-9, NeXTSTEP, and various Unix-like operating systems.

Variants of MicroEMACS also exist, such as mg, a more GNU Emacs-compatible editor. Many relationships to contemporary editors can also be found in MicroEMACS. The vi clone vile was derived from an older version of MicroEMACS.

University of Washington's simple text editor Pico was based on MicroEMACS 3.6. Pico's featureset and interface would later be emulated in the free software clone GNU nano due to its ambiguous licensing terms.{{cite web |title=Man page for Alpine pico(1) |url=https://manpages.debian.org/unstable/alpine-pico/pico.alpine.1.en.html |website=Debian Manpages |access-date=4 August 2020}}

Linus Torvalds, creator of Linux, has been a user of MicroEMACS since his days as a student at the University of Helsinki.{{cite web |title=An Interview With Linus Torvalds: Linux and Git |url=https://www.tag1consulting.com/blog/interview-linus-torvalds-linux-and-git |website=tag1consulting |date=28 April 2021 |access-date=28 April 2021 |quote="I use this abomination called "micro-emacs", which has absolutely nothing to do with GNU emacs except that some of the key bindings are similar."}} Torvalds also maintains [https://github.com/torvalds/uemacs a fork of MicroEMACS].
