city, Providence county, northern Rhode Island, U.S., on the Blackstone River just south of the Massachusetts border. The first European occupation of the site was made by Richard Arnold, who built a sawmill in 1666; his brother John built a house there in 1695. Waterpower brought industrial development: a cotton-spinning mill was built there about 1810, and the first plant for spinning and weaving wool was erected by Edward Harris in 1840. Many of Woonsocket's residents are of French Canadian ancestry; their forebears came from Canada to work in the textile industry. French is still the second language of the city. Woonsocket, once part of Cumberland and Smithfield and not set off as a separate town until 1871, was incorporated as a city in 1888. Textile manufacturing has declined but is still a leading industry. Clothing, electronic products, machinery and machine tools, and plastic goods also are produced. Pop. (1990) 43,877; (2000) 43,224.
