Webster is a town in Worcester County, Massachusetts, United States. The population was 17,776 at the 2020 census.

Named after statesman Daniel Webster, the town was founded by industrialist Samuel Slater, and was home to several early American textile mills. It is home to the Chaubunagungamaug Reservation of the Nipmuc, as well as Lake Chaubunagungamaug, the third largest body of freshwater, and largest natural lake, in Massachusetts.

The area that is now Webster was the ancestral home of the Nipmuc people for thousands of years. It was first colonized by Europeans in 1713 and was officially incorporated on March 6, 1832. The area forming the town had previously been divided among the town of Dudley, the town of Oxford and an unincorporated gore. The primary founder was the manufacturer Samuel Slater, who came to the area after his celebrated activities in Pawtucket, Rhode Island, and founded several textile mills, one of which was taken over by the Cranston Print Works in 1936. He named the town after his friend Daniel Webster. Slater spent his last years in Webster and died and is buried there in Mount Zion Cemetery.

According to the U.S. Census Bureau, the town has a total area of 14.5 square miles (38 km), of which 12.5 square miles (32 km) is land and 2.0 square miles (5.2 km), or 14.10%, is water.

The town is bounded on the north by Oxford; on the east by Douglas; on the south by Thompson, Connecticut, and on the west by Dudley, with which it is most closely tied culturally and politically.

The town is home to Lake Chargoggagoggmanchauggagoggchaubunagungamaugg, also known as Lake Chaubunagungamaug or simply "Webster Lake", the third largest lake in Massachusetts. The 45-character name is often regarded as the longest place name in the United States of America and the third longest in the world.
