Płock County (Polish: powiat płocki) is a unit of territorial administration and local government (powiat) in Masovian Voivodeship, east-central Poland. It came into being on January 1, 1999, as a result of the Polish local government reforms passed in 1998. Its administrative seat is the city of Płock, although the city is not part of the county (it constitutes a separate city county). The county contains three towns: Gąbin, 17 km (11 mi) south of Płock, Drobin, 29 km (18 mi) north-east of Płock, and Wyszogród, 39 km (24 mi) south-east of Płock.
