Leet is a slang term used primarily on the Internet, particularly in online games. It is derived from the word "Elite" and generally has the same meaning when referring to the skills of another person. The term is often written with numbers replacing letters, such as 1337, l33t, l33+, as well as many other variations.

Leet can be defined as the corruption or modification of written text. For example, the term "leet" itself is often written "l33t" or "1337". Such corruptions are frequently referred to as "Leetspeak". In addition to corruption of standard language, new colloquialisms have been added to the parlance. It is also important to note that Leet itself is not solely based upon one language or character set. Greek, Russian, Chinese, and other languages have been subjected to the Leet "cipher". As such, while it may be referred to as a "cipher", a "dialect", or a "language", Leet does not fit squarely into any of these categories. This article primarily concerns the English Language variant of Leet.
