The Institute of National Remembrance – Commission for the Prosecution of Crimes against the Polish Nation (Polish: Instytut Pamięci Narodowej – Komisja Ścigania Zbrodni przeciwko Narodowi Polskiemu, abbreviated IPN) is a Polish state research institute in charge of education and archives with investigative and lustration powers. The IPN was established by the Polish parliament by the Act on the Institute of National Remembrance of 18 December 1998, which incorporated the earlier Main Commission for the Prosecution of Crimes against the Polish Nation of 1991. IPN itself had replaced a body on Nazi crimes established in 1945.

In 2018, IPN's mission statement was amended by the controversial Amendment to the Act on the Institute of National Remembrance to include "protecting the reputation of the Republic of Poland and the Polish Nation". The IPN investigates Nazi and Communist crimes committed between 1917 and 1990, documents its findings, and disseminates them to the public. Some scholars have criticized the IPN for politicization, especially under Law and Justice governments.

The IPN began its activities on 1 July 2000. The IPN is a founding member of the Platform of European Memory and Conscience. Since 2020, the IPN headquarters have been located at Postępu 18 Street in Warsaw. The IPN has eleven branches in other cities and seven delegation offices.
