List of official languages by country

This is a complete list of the official languages of countries and dependent territories of the world. 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: one 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: one designated as having official status limited to a specific area, administrative division, or territory of the state (on this page a regional language will have parentheses next to it that contain a region, province, etc. where the language has regional status)
 * Minority language: (as used here) one spoken by a minority population within the state and officially designated as such; typically afforded protection and designated an officially permissible language for legal and government business in a specific area or territory of the state (on this page a minority language will be followed by parentheses that identify its minority status)
 * National language: one that uniquely represents the national identity of a state, nation, and/or country and so designated by a country's government; some are technically minority languages (on this page a national language will be followed by parentheses that identify it as a national language status). Some countries have more than one language with this status
