Naples is a small unincorporated community in Boundary County, 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 also 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 happened about 8 miles (13 km) from the city.
The name derives from the area in Italy, which was home to many of the laborers who helped build the first rail line through the region around 1890. The town primarily consists of a K-5 school system, the Naples General Store (which also serves as the Post Office), a bar, and a lumber plant.
