The Harbours, Docks and Piers Clauses Act 1847 (10 & 11 Vict.

c. 27) is an act of Parliament of the United Kingdom which governs harbours, docks and piers.

The act allows two justices of the peace to swear in port police officers as "special constables" with jurisdiction within the limits of the harbour, dock, pier and premises of the port company, and within one mile of the same.

Officers of approved port police forces were issued with the faithful service medal after the qualifying period of service.
