Penzance Borough Police was the police force for the borough and corporate town of Penzance, Cornwall, from 1836 to 1947. It was formed following the passing of the Municipal Corporations Act 1835, which reformed all UK boroughs, and stipulated that each appoint a Watch Committee to oversee a police force. The police force formed part of the commonality of the town's government, led by an elected Mayor, six aldermen and eighteen councillors.
