Princeton is a town located in Worcester County, Massachusetts. The town was created in 1759, out of land that was once part of Rutland. In 1810, it annexed a piece of Hubbardston, and in 1870, it annexed a piece of Westminster. It is bordered on the east by Sterling and Leominster; on the north by Westminster; on the west by Hubbardston and Rutland; on the south by Rutland and Holden. The preeminent landmark within Princeton is Mount Wachusett, which straddles the line between Princeton and Westminster but the entrance to which is within Princeton.
