The Volhynian Crime portal is an educational and historical resource of Poland’s Institute of National Remembrance (IPN), dedicated to documenting and explaining the mass violence against Poles carried out by Ukrainian nationalists during 1943–1945. It presents the events as an anti-Polish ethnic cleansing with the character of genocide, extending beyond Volhynia into Eastern Galicia and neighboring areas. The portal brings together historical articles, archival materials, photographs, documentary films, discussions, and publications related to the crime and its consequences.

Visitors can explore accounts from witnesses, information about Ukrainians who helped Polish neighbors, and materials on investigations into the events. Its resources include a searchable database containing nearly 49,000 entries concerning people, families, and incidents, as well as maps, galleries, and a reading section. News and recommended content highlight new research, commemorations, and IPN activities.

Designed to support learning and remembrance, the portal organizes its content into accessible sections on history, witnesses, investigations, victims, and multimedia, and offers interfaces in Polish, English, and Ukrainian
