List of territorial entities where English is an official language

The following is a list of territories where English is an official language, that is, a language used in citizen interactions with government officials. In 2015, there were 54 sovereign states and 27 non-sovereign entities where English was an official language. Many country subdivisions have declared English an official language at the local or regional level.

The majority of countries where English is an official language are former territories of the British Empire. Notable exceptions include Rwanda, which was formerly a Belgian territory, and Eritrea, which was an Italian colony where the British Empire maintained control only in World War II and shortly after (1941–1952). English is the sole official language of the Commonwealth of Nations. English is one of the official languages of the United Nations, the European Union and the International Olympic Committee. Although English is not an official language at the national level in the United States, many states and territories within the United States have English as an official language.

The United Kingdom, 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 to be their de facto official language due to its historical and widespread use in these nations.

In these country subdivisions, English has de jure official status, but English is not official in their respective countries at the national level.
