List of official languages by country and territory

This is a list of official languages by country and territory. It includes all languages that have official language status either statewide or in a part of the state, or that have status as a national language, regional language, or minority language.

Definitions

 * Official language: A language designated as having a unique legal status in the state: typically, the language used in a nation's legislative bodies, and often, official government business.
 * Regional language: A language designated as having official status limited to a specific area, administrative division, or territory of the state. (On this page a regional language has parentheses next to it that contain a region, province, etc. where the language has regional status.)
 * National language: A language that uniquely represents the national identity of a state, nation, and/or country and is so designated by a country's government; some are technically minority languages. (On this page a national language is followed by parentheses that identify it as a national language status.) Some countries have more than one language with this status.

Number of countries with the same official language
This is a ranking of languages by number of sovereign countries in which they are de jure or de facto official, although there are no precise inclusion criteria or definition of a language. An '*' (asterisk) indicates a country whose independence is disputed.

Partially recognized or de facto independent countries are denoted by an asterisk (*)
