Crooswijk (Dutch pronunciation: [ˈkroːsʋɛik]) is a neighborhood of Rotterdam, Netherlands.
Crooswijk lies between the districts Kralingen, Oude Noorden and Centrum.
Many streets bear witness to a military history of the Marine Corps: Tamboerstraat, Pijperstraat, Schuttersveld, Excercitiestraat, Vaandrigstraat.
Crooswijk is one of the original people's neighborhoods of Rotterdam (unlike many other people's neighborhoods in the city, which originally were independent villages) and the district is strongly associated with the 'real' Rotterdammer.
Crooswijkers sought and seek their recreation at the nearby Kralingse bos.
