The Izaak Walton Inn is a historic inn in Essex, Montana, USA. It was originally built as the Izaak Walton Hotel in 1939 by the Great Northern Railway as a soup kitchen and lodgings for railway workers. The hotel was also originally envisioned as a potential official southern gateway to Glacier National Park, hence its size, but World War II intervened and that plan never materialized. Today, the inn is served by Essex station, the only request stop on Amtrak's Empire Builder route. A van from the inn meets both the morning eastbound and the evening westbound Empire Builders to convey passengers between the station and the inn.
