Fort Benton Historic District, Historic waterfront district in Fort Benton, Montana, US.

Fort Benton Historic District is a riverside district along Front Street featuring structures dating from the era when this was a major trading hub, including a bridge from the 1880s. The area contains museums, a reconstructed fort structure, and interpretive centers that explain the original purpose and operations of this location.

Alexander Culbertson of the Chouteau brothers firm founded Fort Benton in 1846–1848 as a palisaded fur trading post named for Senator Thomas Hart Benton. Keelboats first carried goods; in 1859 the Chouteaus began steamboat service from St. Louis. From 1860 to 1890 it was a principal embarkation point for Western supplies, and goods also went north to Edmonton. River trade declined late in the century as railroads proved more reliable.

The district reflects how traders and settlers lived and worked at this river port, with buildings that tell of fur trade networks and frontier commerce. Museums here preserve stories of trading relationships and daily life in this remote outpost.

The district is easily explored on foot with multiple buildings and museums accessible at a relaxed pace over a few hours. Interpretive signs throughout the area help visitors understand what each building was and how it functioned in the trading port.

The 1856 blockhouse is the only surviving structure of the original fur trading post; the rest of the fort is gone. The district also holds the 1867 I.G. Baker House, the oldest surviving residence in the district, and the 1888 Fort Benton Bridge, built by local merchants trying to keep the city's trade alive as steamboats declined.
