In the history of Poland, a royal city or royal town (Polish: miasto królewskie) was an urban settlement within the crown lands (Polish: królewszczyzna).
The most influential royal cities enjoyed voting rights during the free election period in Poland (1572-1791). These cities were Gdańsk, Warsaw, Kraków, Poznań, Lwów, Wilno, Toruń, Lublin, Kamieniec Podolski and Elbląg. Other important royal cities included Gniezno (ecclesiastical capital of Poland and former capital of early medieval Poland), Płock (former capital of medieval Poland), Grodno (general sejm location alongside Warsaw), Bydgoszcz and Piotrków (Crown Tribunal locations alongside Lublin).
On April 18, 1791, the Great Sejm adopted the Free Royal Cities Act (full title: "Miasta nasze królewskie wolne w państwach Rzeczypospolitej" - "Our Free Royal Cities in the States of the Commonwealth"), included as Article III into the Constitution of May 3, 1791.
