Grafton is a town in Windham County, Vermont, United States. The population was 645 at the 2020 census.

In the early 19th century, sheep raising became popular and multiple woolen mills sprang up along the branches of the Saxtons River. Soapstone was quarried on nearby Bear Mountain. The town became a notable stagecoach hub for traffic across the Green Mountains into Albany, New York. One inn from that era, "the Old Tavern," was founded in 1801. It remains one of the oldest continually operating hotels in the United States. It's now called The Grafton Inn.

Grafton had a population of almost 1,500 just before the American Civil War. The town suffered severe losses during the Civil War. Local cemeteries in the village hold many tombstones of casualties from the Battle of Gettysburg. After the war, the community declined in population. The soapstone quarry was depleted and closed late in the 19th century. Around the time of the Great Depression, the town's population was less than 400.

In the 1960s the Windham Foundation was established to help restore the village. It purchased the Old Tavern and many residences in the area. The foundation also established an artisanal cheese business, the Grafton Village Cheese Company, and built a world-class cross-country skiing center at Grafton Ponds that offers a popular mountain biking program for children in the summer months. The restoration efforts attracted new residents from metropolitan New York and Boston.

The town was founded as Thomlinson in 1754, but renaming rights were auctioned in 1791. The high bidder, who reportedly offered "five dollars and a jug of rum," changed the name to Grafton after his home town of Grafton, Massachusetts.

According to the United States Census Bureau, the town has a total area of 38.4 square miles (99.5 km), of which 38.4 square miles (99.4 km) is land and 0.03% is water. The village of Grafton is slightly southeast of the geographic center of the town, in the valley of the Saxtons River.
