The map–territory relation is the relationship between an object and a representation of that object, as in the relation between a geographical territory and a map of it. Mistaking the map for the territory is a logical fallacy that occurs when someone confuses the semantics of a term with what it represents. Polish-American scientist and philosopher Alfred Korzybski remarked that "the map is not the territory" and that "the word is not the thing", encapsulating his view that an abstraction derived from something, or a reaction to it, is not the thing itself. Korzybski held that many people do confuse maps with territories, that is, confuse conceptual models of reality with reality itself. These ideas are crucial to general semantics, a system Korzybski originated.
The relationship has also been expressed in other terms, such as "the model is not the data", "all models are wrong", and Alan Watts's "The menu is not the meal." The concept is thus quite relevant throughout ontology and applied ontology regardless of any connection to general semantics per se (or absence thereof). Its avatars are thus encountered in semantics, statistics, logistics, business administration, semiotics, and many other applications.
