Hobson is a city in Judith Basin County, Montana, United States. The population was 179 at the 2020 census. As the freight-wagon crossing of the Judith River between Fort Benton, Montana and the Musselshell River country, the community was once known as the “Gateway to the Judith Basin.” In 1881, the post office opened under the name Philbrook. In 1908, however, the Great Northern Railway’s Billings and Northern branch line established another town four miles west. After some dispute the railroad decided on the town name Hobson, after the owner of the new townsite.
Its first post office opened in 1912. Between the 2010 and 2020 censuses its population fell from 215 to 179 (-17%).
