IV liga (Czwarta liga) is the fifth level of the Polish football league system. The current structure of IV liga was created in season 2000/01 after introducing new administrative division of Poland. 16 clubs, one from each voivodeship (province), are promoted to III liga. The bottom clubs are relegated to Liga okręgowa or V liga (depending on the voivodeship).
Until the end of the 2007/08[1] season IV liga lay at fourth tier of league system but this was changed with the formation of the Ekstraklasa as the highest level of football league in Poland.
