The far-right Vlaams Belang (Flemish Interest) is the most militant Flemish regional party, with a separatist, anti-immigration, law and order platform. The Vlaams Belang was formerly called the Vlaams Bloc, until a 2004 high court ruling confirmed a lower court verdict that the Bloc was a "racist" party. Faced with further legal problems, the Bloc disbanded and resurrected itself as the Vlaams Belang, with the same party leaders and basically the same radical party policy. The Vlaams Belang was the second most popular party in the 2007 general elections, with 19% of the Flemish vote.

In Brussels and Wallonia, the small far-right Front National (FN) managed to hold on to its only House seat in the 2007 general elections.

The now-defunct Volksunie Party (VU) was the most militant Flemish regional party in Parliament in the 1950s and 1960s, drawing nearly one-quarter of Belgium's Dutch-speaking electorate at the height of its popularity. However, as much of the VU's nationalist agenda was realized through subsequent constitutional reforms that saw the devolution of significant power to the regions, the VU suffered severe setbacks. It ultimately splintered into a traditional Flemish nationalist faction, the NVA (currently in alliance with the CD&V), and a more liberal faction, Spirit (in an electoral alliance with the Flemish Socialist Party).
