Essex station is a stop on Amtrak's Empire Builder line in Essex, Montana. Essex has a year-round population of less than 50; most passengers are visitors to the nearby historic Izaak Walton Inn located about 3⁄10 mile (0.48 km) away.

There currently is no station building at Essex, passengers are shuttled directly to the Inn.

Essex is a flag stop. That is, the stop is skipped in the event that there are no passengers listed in Amtrak’s digital reservation system to alight or board at the station.

Between 1970 and 1985 there were no regular stops at Essex. In late 2010, Amtrak built a concrete platform with embedded heating coils for automatic snow clearance to replace the former asphalt platform, and also added additional lighting and fencing.
