Warren is a town located in Washington County within the state of Vermont, United States. Situated between the two ranges of the Green Mountains, the community occupies a significant portion of federal land, with approximately twenty-five percent of its boundaries falling within the Green Mountain National Forest. The center of population for the entire state of Vermont is located within this town, highlighting its geographic centrality in the region.

The area was granted on November 9, 1780, and officially chartered on October 20, 1789, to John Throop and sixty-seven others. It was named for Dr. Joseph Warren, a patriot of the Revolutionary War. The first settlers, Samuel Lard and Seth Leavitt, arrived in 1797 to establish grain and lumber mills on the Mad River. By 1839, the town supported a population of 766 people who grazed cattle and sheep while producing milk and maple syrup.

The landscape is defined by the Mad River, a tributary of the Winooski River that flows toward Lake Champlain. Sugarbush Resort serves as a major local landmark, having evolved from a ski tow erected in the late 1930s into a prominent tourist destination. The Long Trail, a hiking path extending from Massachusetts to the Canadian border, traverses the town. The historic Warren Covered Bridge is also listed as a notable site of interest within the community.

Recreational skiing began developing in the area during the late 1930s, with the first tow built by the Warren Outing Club. In 1958, Damon Gadd and Jack Murphy founded Sugarbush Ski Area on Lincoln Peak, installing a three-seat gondola that was then the nation's longest lift. This development transformed the local economy into one focused on tourism, drawing visitors to the resort and the surrounding natural environment for outdoor activities.

The population of Warren was 1,977 as of the 2020 census. The town covers a total area of forty square miles, with the vast majority being land. It is crossed by Vermont Route 100 and served by the Warren-Sugarbush Airport. Historical demographic data from 2000 indicated a median age of forty years and a racial makeup that was predominantly white, with a median household income of $47,438 at that time.
