National Socialist Bloc (Swedish: Nationalsocialistiska Blocket) was a Swedish Nazi political party formed in the end of 1933 by the merger of Nationalsocialistiska Samlingspartiet, Nationalsocialistiska Förbundet and local National Socialist units connected to the advocate Sven Hallström in Umeå.
Later Svensk Nationalsocialistisk Samling merged into NSB.
The party maintained several publications, Landet Fritt (Gothenburg), Vår Kamp (Gothenburg), Vår Front (Umeå), Nasisten (Malmö) and Riksposten.
NSB was clearly smaller than the two main Nazi parties in Sweden at the time, SNSP and NSAP.
