Treaty of Radnot was a treaty signed during the Second Northern War in Radnot in Transylvania (now Iernut in Romania) on 6 December 1656. The treaty divided the Polish–Lithuanian Commonwealth between the signing parties.
According to the treaty:
One of the main results of the treaty was that George II Rákóczi invaded the Commonwealth in January 1657. Due to changed geopolitical situation the treaty was never fully implemented, as the Commonwealth recovered and threw out the invaders. The treaty is seen as a precursor to the 18th-century partitions of Poland.
