This is a list of wars involving the United Kingdom of Great Britain and Northern Ireland and its predecessors the United Kingdom of Great Britain and Ireland and the Kingdom of Great Britain and the Kingdom of Ireland and generally the British Isles. Notable militarized interstate disputes are included.

The Kingdom of Great Britain was formed in 1707 through the Acts of Union 1707, which united the kingdoms of England and Scotland into a single kingdom encompassing the whole island of Great Britain and its outlying islands. It did not include the Kingdom of Ireland, which although under British control, remained a separate realm. On 1 January 1801, the kingdoms of Great Britain and Ireland were merged to form the United Kingdom of Great Britain and Ireland. In 1922, five-sixths of Ireland seceded from the United Kingdom and the state was renamed the United Kingdom of Great Britain and Northern Ireland.

During its history, British 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]
