The Izaak Walton Inn is a historic inn in Essex, Montana, USA. It was originally built by the Great Northern Railway in 1939 for lodging railway workers. In addition to railway lodging, the hotel was also originally envisioned as a potential official southern gateway to Glacier National Park, but that plan never materialized. Today, the inn is at 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 Essex station and the inn.
