The Polish War Memorial is a memorial erected in England to remember the contribution of airmen from Poland who helped the Allied cause during the Second World War. It is situated beside the A40/A4180 roundabout junction near RAF Northolt in South Ruislip in the London Borough of Hillingdon. The Polish War Memorial is often used by locals as a landmark when giving directions and in broadcasts of traffic reports, as it is prominently situated by a major road junction on one of the main routes into London.
