The former Royal Air Force Rheindahlen, more commonly known as RAF Rheindahlen, was a non-flying Royal Air Force (RAF) military administrative base, becoming part of the Rheindahlen Military Complex in North Rhine-Westphalia, Germany; collectively a part of British Forces Germany (BFG). The Royal Air Force station was named after the nearby town and railway station of Rheindahlen. In the 1950s and 1960s, it was more commonly referred to as RAF Mönchengladbach; due to Rheindahlen being the Army's name for the same JHQ. It was unusual in that the RAF station land was publicly accessible, with public transport routes, and even German civilian mail service.
