Holland is a town in Hampden County, Massachusetts, United States. The population was 2,603 at the 2020 census. It is part of the Springfield, Massachusetts Metropolitan Statistical Area.

The area around the town center comprises the census-designated place of Holland.

In 1730, the area that would become the town of Holland was settled by Joseph Blodgett, whose descendants still live in the town today. The town was named after Lord Holland, an English statesman who lobbied for independence for the American colonies. The town was incorporated on July 5, 1783. It separated from the town of Wales, which had in turn separated from Brimfield a few years earlier, in 1775. Holland separated from Wales because the town center of Wales was up through a mountain which made it hard to get through.

Throughout the years, Holland has remained an example of the charm and beauty of the traditional New England village. At different times, it has sustained industries such as farming, the manufacturing of cloth, and brickmaking. Holland is now known most for its recreational opportunities. There are extensive recreational facilities at the Hamilton Reservoir, which is stocked with trout each year by the state of Massachusetts. There is also a park and a swimming area at the picturesque Lake Siog.

The 200-year-old town hall was destroyed in a fire in December 1995. The new town hall was dedicated on July 11, 1998, by Congressman Richard Neal of Springfield, whose congressional district includes Holland.

Holland is located in the southeast corner of Hampden County in western Massachusetts. It is drained by the Quinebaug River and contains the Hamilton Reservoir, one of the largest reservoirs in southern New England. The town is nestled amongst two hill ranges, where elevations reach up to greater than 1,100 feet (340 m), for example on Rattlesnake Mountain in the northwest part of town.

According to the United States Census Bureau, the town has a total area of 13.1 square miles (33.8 km), of which 12.3 square miles (31.8 km²) are land and 0.77 square miles (2.0 km), or 5.88%, are water. Holland is bounded on the east by Sturbridge in Worcester County, on the south by Union, Connecticut, on the west by Wales, and on the north by Brimfield.
