The Five Eyes (FVEY) is an Anglosphere intelligence alliance comprising Australia, Canada, New Zealand, the United Kingdom, and the United States.[1] These countries are party to the multilateral UK-USA Agreement, a treaty for joint cooperation in signals intelligence.[2][3][4] Informally, "Five Eyes" can refer to the group of intelligence agencies of these countries. The term "Five Eyes" originated as shorthand for a "AUS/CAN/NZ/UK/US Eyes Only" (AUSCANNZUKUS) releasability caveat.[5]

The origins of the FVEY can be traced to informal, secret meetings during World War II between British and American code-breakers that took place before the US formally entered the war.[6] The alliance was formalized in the post-war era by the UKUSA Agreement in 1946. As the Cold War deepened, the intelligence sharing arrangement was formalised under the ECHELON surveillance system in the 1960s.[7] This system was developed by the FVEY to monitor the communications of the Soviet Union and Eastern Bloc; it is now used to monitor communications worldwide.[8][9] The FVEY expanded its surveillance capabilities during the course of the "war on terror", with much emphasis placed on monitoring the Internet. The alliance has grown into a robust global surveillance mechanism, adapting to new domains such as international terrorism, cyberattacks, and contemporary regional conflicts.

The alliance's activities, often shrouded in secrecy, have occasionally come under scrutiny for their implications on privacy and civil liberties, sparking debates and legal challenges. In the late 1990s, the existence of ECHELON was disclosed to the public, triggering a debate in the European Parliament and, to a lesser extent, the United States Congress and British Parliament. Former NSA contractor Edward Snowden described the Five Eyes as a "supra-national intelligence organisation that does not answer to the known laws of its own countries".[10] 2010s global surveillance disclosures revealed FVEY was spying on one another's citizens and sharing the collected information with each other, although the FVEY nations maintain this was done legally.[11][12]

Five Eyes is among the most comprehensive espionage alliances.[13] Since processed intelligence is gathered from multiple sources, the information shared is not restricted to signals intelligence (SIGINT) and often involves military intelligence (MILINT), human intelligence (HUMINT), and geospatial intelligence (GEOINT). Five Eyes remains a key element in the intelligence and security landscape of each member country, providing them a strategic advantage in understanding and responding to global events.
