Hudson is a town in Middlesex County, Massachusetts, United States. The town is located in central Massachusetts, about a 40-minute drive, or about 30 miles (48 km) , west of Boston, and about a 20-minute drive, or about 16.5 miles (26.6 km) , northeast of Worcester. Before its incorporation as a town in 1866, Hudson was a suburb of the neighboring Marlborough, Massachusetts, and was known as Feltonville. From around 1850 until the last shoe factory burned down in 1968, Hudson was known as a "shoe town." At one point, the town had 17 shoe factories, many of them powered by the Assabet River, which runs through town. Because of the many factories in Hudson, immigrants were attracted to the town. Today, most people are of either Portuguese or Irish descent, with a smaller percentage of people being of French, Italian, English, or Scots-Irish descent. Hudson is served by the Hudson Public Schools district.
