The Nationalistische Studentenvereniging (NSV) (Dutch; "Nationalist Student Association") is a far-right Flemish nationalist student political group in Belgium, with chapters in Antwerp, Brussels, Ghent, Leuven, West Flanders (including Bruges, Roeselare, Ostend and Kortrijk), Hasselt and Mechelen.

The NSV was founded in 1976 by Edwin Truyens as a radical splinter group of the Katholiek Vlaams Hoogstudentenverbond (KVHV; "Catholic Flemish Student Union").

[1] Smaller numbers of former NSV members have also been elected to office for the newer and more moderate New Flemish Alliance party.

[2] Internationally the NSV maintains informal relations with several European nationalist organizations, such as Generation Identity, the Movimento Giovani Padani and the publishing house Arktos.

The black relates to the Flemish flag, and white and red are the heraldic colours of Antwerp, the city where the NSV was founded.
