Porthill is an unincorporated community in Boundary County, Idaho, United States, located at the Canada–United States border into British Columbia.
Idaho State Highway 1 runs straight through the community and to the Porthill-Rykerts Border Crossing, and then becomes British Columbia Highway 21, which continues north towards Creston. The Porthill-Rykerts Border Crossing is used as the American Port only; Rykerts acts as the Canadian Crossing.
The north-flowing Kootenai River is just west of Porthill.
