Piotrków County (Polish: powiat piotrkowski) is a unit of territorial administration and local government (powiat) in Łódź Voivodeship, 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 Piotrków Trybunalski, although the city is not part of the county (it constitutes a separate city county). The only towns in Piotrków County are Sulejów, which lies 15 km (9 mi) east of Piotrków Trybunalski, and Wolbórz (classed as a town since 1 January 2011).
