Emacs, originally named EMACS, is a family of text editors that are characterized by their extensibility. The manual for the most widely used variant, GNU Emacs, describes it as "the extensible, customizable, self-documenting, real-time display editor". Development of the first Emacs began in the mid-1970s, and work on GNU Emacs, directly descended from the original, is ongoing; its latest version is 29.3, released March 2024.

Emacs' interface was influenced by the design of the space-cadet keyboard, which sought to enable users to type as many different kinds of input as possible.
