Shrewsbury is a town in Worcester County, Massachusetts, United States. Shrewsbury, unlike the surrounding towns of Grafton, Millbury, Westborough, and Northborough, did not become a mill town or farming village; most of its 19th-century growth was due to its proximity to Worcester and visitors to Lake Quinsigamond. The population was 38,325 according to the 2020 US Census, in nearly 15,000 households.
Incorporated in 1727, the town is governed now under the New England representative town meeting system, headed by the Town Manager and five-member elected Board of Selectmen whose duties include licensing, appointing various administrative positions, and calling a town meeting of citizens annually or whenever the need arises.
