Naples is a small unincorporated community in Boundary County, in the far north of Idaho, United States. It lies 11 miles (18 km) south of the city of Bonners Ferry and 23 miles north of Sandpoint, on U.S. Routes 2/95 in the Rocky Mountains. It is very close to the US-Canada border.
Naples is near the land features of Caribou Ridge and Ruby Creek. The Ruby Ridge standoff of 1992, between federal agencies and the Randy Weaver family, took place about 8 miles (13 km) from the city.
