The Sumpter Valley Railway Passenger Station is a historic train station in Prairie City, Oregon. It was constructed in 1910 to serve as the westernmost stop of the Sumpter Valley Railway that ran from Baker City to Prairie City.

The Sumpter Valley Railway Passenger Station in Prairie City was abandoned in 1933 due to the loss of business caused by the advent of automobiles and trucks. The beautiful Queen Anne building was then sold and used as a private residence for a time until the city acquired the property and transformed it into the DeWitt Museum.

Today, the Sumpter Valley Railway Passenger Station continues to house the DeWitt Museum, which is mostly about the town?s railway history. It features railway artifacts and life at the rail line. They also feature a collection of rocks, minerals, mining artifacts, and some family photo albums.
