The current Constitution of Poland was founded on 2 April 1997. Formally known as the Constitution of the Republic of Poland (), it replaced the Small Constitution of 1992, the last amended version of the Constitution of the Polish People's Republic, known from December 1989 as the Constitution of the Republic of Poland.
