Seekonk is a town in Bristol County, Massachusetts, United States, on the Massachusetts border with Rhode Island. It was incorporated in 1812 from the western half of Rehoboth. The population was 15,531 at the 2020 census. Until 1862, the town of Seekonk also included what is now the City of East Providence, Rhode Island, as well as the section of the City of Pawtucket, Rhode Island east of the Blackstone River. The land in the western half of the town was given to Rhode Island by the United States Supreme Court as part of a longstanding boundary dispute with Massachusetts.
