The Treaty Ports were three harbour installations retained by the United Kingdom as military bases and sovereign territory after the establishment of the Irish Free State on December 6, 1922. These were located in Lough Swilly, Berehaven and Queenstown, today known as Cobh. The were also provisions for Belfast Lough to remain under British control, but as Northern Ireland exercised its right to opt out the Irish Free State on December 8, 1922 the entire territory remained within the United Kingdom.

In 1938 control over the Treaty Ports were handed over to Ireland and they ceased to be British territory.
