Orange was first settled by Europeans in 1746, created from lands in the towns of Royalston, Warwick and Athol. The lands were not fully settled until the latter parts of the century, becoming the District of Orange in 1783, and finally being incorporated as a town in 1810. It was named for William, Prince of Orange. In 1790, the Millers River was dammed within town, and industry began in the former farming community. Small industry grew within the town, with the town being considered more of a mill town by 1840. By the late nineteenth century the New Home Sewing Machine Company was the largest industry in town, putting out 1.2 million machines at its peak in 1892. In 1900, it was home to the pioneer automobile company Grout, considered the first automobile built in a factory in the United States.

The town was used as the eponymous location for the Hulu Castle Rock series, based on Steven King’s works, with several businesses in the downtown refitted to reflect the milieu.

The Massachusetts Peace Statue—It Shall Not Be Again—a bronze war memorial statue was erected in Memorial Park in 1934 to recognize veterans who served in World War I. On February 25, 2000 the legislature designated it the official peace statue of the Commonwealth of Massachusetts.
