List of wars involving the United Kingdom
This is a list of conflicts involving the United Kingdom of Great Britain and Northern Ireland and its predecessor states (the Kingdom of Great Britain, Kingdom of England, Kingdom of Scotland and generally the British Isles). Notable militarised interstate disputes are included. For a list of wars before the Acts of Union 1707 please see List of wars involving England & List of wars involving Scotland.

During its history, the United Kingdom's forces (or forces with a British mandate) have invaded, had some control over or fought conflicts in 171 of the world's 193 countries that are currently UN member states, or nine out of ten of all countries.[1]
