This is a list of army divisions serving within the British Empire during the Second World War. Military formations within the British Empire were generally not static and were composed of a changing mix of units from across Britain, its colonies and the dominions. As a result military formations within the Empire and Commonwealth are not easily attributable to specific Imperial or national entities and naming conventions do not necessarily correlate with modern country names.
