Marshfield, Vermont is a town in Washington County, in the Waterbury-Montpelier region. The Independent Republic of Vermont chartered the Town of Marshfield in 1790 and named it for Isaac Marsh, one year before Vermont became the 14th state to join the union.
The Groton State Forest, established in 1919, is located along the town's eastern border. From 1933 until 1941 the Civilian Conservation Corps built park shelters and hiking trails to provide year-round recreational opportunities. The CCC also worked on forestry projects and constructed a permanent road through the forest to the town of Groton.
The old stagecoach road along the Winooski River, known as the River Road, was paved in 1932 between Plainfield and Marshfield and given the designation U. S. Route 2. Automobile travelers vacationed overnight at five private tourist cabin locations along the highway. Electric lines reached local houses and barns in the late 1930s, and in the early 1950s bulk milk tanks were introduced to the dairy farms.
Portions of the 1983 film adaptation of Robert Cormier's novel I Am the Cheese were filmed in Marshfield.
