Whitinsville is an unincorporated village within the town of Northbridge in Worcester County, Massachusetts, United States.

Whitinsville has been designated as a mill village of national historic significance to America's earliest industrialization, and is one of only four villages selected by the John H. Chaffee Blackstone River Valley National Historic Corridor Commission to receive this designation.

Col. John Spring led a militia training company from Uxbridge which fought in the American Revolution.

Today a visitor can see much of the original village, including the housing for workers and their families, churches, and the Whitin Community Center.

The textile machine company and industrial village were written up as one of the Harvard studies of history in business.

A 1936 Berlin Olympics champion backstroke swimmer, Alice Bridges, then of Uxbridge, trained in the local gym pool (Whitin Community Center) in Whitinsville.

A real estate transaction two years earlier had failed to disclose termites in a building.

This recreation center, known affectionately in earlier days as "The Gym," was one of the finest facilities in the state.

Devastated by fire in 1959, the Gym was rebuilt with the support of trustees, business and civic leaders, and friends.

The decade of the 1990s was dedicated to expanding and modernizing the Whitin Community Center to prepare it for the 21st century.

In 1993 new space was added to strengthen the center's commitment to child care and adult health and fitness.

A new lobby, elevator, and racquetball courts completed this expansion phase, and most of the original 1922 building received a comprehensive face lift.

This new facility opened briefly as an outdoor pool (summer 1998) and then was enclosed for year-round use, reopening in March 1999.

In the location of an original Whitin estate building – the rustic teahouse – the Gerry Gaudette pavilion has been built.

This open air shelter is used by the center's child care and summer camp program, along with use by the community at large.

In January 2002 a new facility opened – the Rockdale Youth Center – providing free after school programs and supervision for youngsters ages 8–13.

New England towns, like Northbridge, administer the entire geography within their boundaries and function like a city and a county government rolled into one.

Police, public works, the board of health, fire department and schools are part of the town government.
