North Narrabeen is a suburb in northern Sydney, New South Wales, Australia 25 kilometres north of the Sydney central business district, in the local government area of Northern Beaches Council.

The extension of tram services to Narrabeen in 1913 provided easier transport, and the whole area around the lake became popular for holidays and camping.

In 1946 the Wakehurst Parkway was opened to North Narrabeen connecting the whole Pittwater area directly to Frenchs Forest and Seaforth.

Prior to World War II, the German Labour Front operated a cottage at Deep Creek to host Nazi Party meetings, as well as more relaxed events for German sailors, officers and other passing Germany dignitaries such as Felix von Luckner.

There were rumours that the camp was used to collect intelligence, but a post-War Defence Department investigation failed to find any evidence of espionage activity.
