The Anglosphere is a set of English-speaking nations with similar cultural roots, based upon populations originating from the nations of the British Isles (England, Wales, Scotland, Northern Ireland, and Ireland), which today maintain close political and military cooperation. While the nations included in different sources vary, the Anglosphere is usually not considered to include all countries where English is an official language, although the nations that are commonly included were all once part of the British Empire. 

In its most restricted sense, the term covers Australia, Canada, Ireland, New Zealand, the United Kingdom, and the United States, which in the post-British Empire era maintain a close affinity of cultural, familial, and political links with one another. 

Additionally, all of these countries (except Ireland) are militarily aligned under the following programs: UKUSA Agreement (signals intelligence), Five Eyes (intelligence), Combined Communications Electronics Board (communications electronics), The Technical Cooperation Program (technology and science), Air and Space Interoperability Council (air forces), AUSCANNZUKUS (navies), and ABCA Armies.
