Voorpost ("outpost, picket") is an ethno-nationalist (volksnationalist) group founded in Flanders, Belgium, by Karel Dillen in 1976 as a splinter from the Volksunie.

[3] Voorpost pursues the irredentist ideal of a Greater Netherlands, a nation state that would unite all Dutch-speaking territories in Europe.

The organisation has staged rallies on various topics, against Islam, leftist organizations, drugs, and socialism.

[9] In 1986, the Dutch labour union FNV and the Anne Frank Foundation made a list of groups it considered racist and fascist which included Voorpost.

A Dutch court ruled in 2012 this ban on Voorpost members was against the law as discrimination based on political opinion is illegal in the Netherlands.
