The following is a list of countries and territories where English is an official language used in citizen interactions with government officials. As of 2020^[update], there were 58 sovereign states and 28 non-sovereign entities where English was an official language.^{[citation needed]} Many administrative divisions have declared English an official language at the local or regional level.

Most states where English is an official language are former territories of the British Empire. Exceptions include Rwanda and Burundi, which were formerly German and then Belgian colonies; Cameroon, where only part of national territory was under British mandate; and Liberia, the Philippines, the Federated States of Micronesia, the Marshall Islands, and Palau, which were American territories. English is the sole official language of the Commonwealth of Nations and of the Association of Southeast Asian Nations (ASEAN). English is one of the official languages of the United Nations, the European Union, the African Union, the Organisation of Islamic Cooperation, the Caribbean Community, the Union of South American Nations, and many other international organisations. Although English is not de jure an official language at the national level in the United States, most states and territories within the United States have English as an official language, and only Puerto Rico uses a language other than English as a primary working language.

The United Kingdom, the United States, Australia, and New Zealand, where the overwhelming majority of native English speakers reside, do not have English as an official language de jure, but English is considered their de facto official language because it dominates in these countries.^{[citation needed]}
