Bozeman Depot is a former train station in Bozeman, Montana, opened in 1883 by the Northern Pacific Railway. The current brick station house was built in 1892 and expanded in 1924.

The first railroad depot in Bozeman opened in 1883 when the transcontinental main line of the Northern Pacific Railway reached the city.

In 1891 a cinder from a passing steam locomotive ignited the wood depot building, causing severe fire damage. The city decided to rebuild at a grander scale since Bozeman was then competing to become the state capital of Montana. Completed in 1892, the new depot featured brick construction and Romanesque elements such as a large central turret.

On July 27, 1892, the Bozeman Street Railway began operating hydroelectric-powered trolleys on a 1.3-mile (2.1 km) route from Bozeman Depot to the corner of Main Street and Grand Avenue. Two extensions brought the system to 3.78 miles (6.08 km) in length by 1901, connecting to Montana State College at Montana Hall. Amid growing competition from automobiles, the system closed on December 15, 1921, when a snowstorm damaged the last trolley car. In 1900 Northern Pacific inaugurated the North Coast Limited, an express train between Chicago and both Seattle and Portland that stopped at Bozeman Depot. The Alaskan ran over the same route but on a slower schedule, making more stops. In 1952 the Alaskan was replaced by the Mainstreeter.

A major expansion and renovation of the depot occurred in 1923–1924, when a wing was added to the southeastern side in order to accommodate increased passenger traffic. Taking Prairie School influences, the central turret was also removed, and the entire façade was clad in red brick.

In 1970 the Northern Pacific merged with the Chicago, Burlington and Quincy Railroad, the Great Northern Railway, and the Spokane, Portland and Seattle Railway, forming the facility's new owner, the Burlington Northern Railroad. Amtrak took over most inter-city passenger rail in the United States on May 1, 1971, including the Burlington Northern routes. The North Coast Limited and Mainstreeter were discontinued. Bozeman was left with no train service until pressure led by Senator Mike Mansfield resulted in Amtrak launching the North Coast Hiawatha in June.

In October 1979 Amtrak discontinued the North Coast Hiawatha due to budget cuts, severing Bozeman and all of southern Montana from the national rail network. This left the Empire Builder as the only passenger rail service in the state, running on the former main line of the Great Northern Railway. Since then, Bozeman Depot has been closed to the public and used primarily for storage.
