Warszawy) is a museum in the Old Town Market Place in Warsaw, Poland.

The museum, along with the collection, was destroyed during the Warsaw Uprising during World War II.

After the war, the museum was reopened under its current name and buildings for it were rebuilt in the years 1948–1954 in the context of the unprecedented reconstruction of historic Warsaw.

The various collections in the fields of archeology, painting, graphics, iconography, sculpture, decorative arts, numismatics and architectural drawings, now exceed 250 000 objects.

Until the start of the renovations in 2010 there was available exhibitions showing seven centuries of Warsaw history, from its foundation to the present day.
