Verdinaso, sometimes rendered as Dinaso, was a small fascist political movement active in Belgium and, to a lesser extent, the Netherlands between 1931 and 1941.

Joris Van Severen was a Belgian politician and ideologue of the Flemish Movement as well as a Pan-Netherlander. A leading figure of pre-World War II Flemish nationalism, he co-founded the extreme-right group Verdinaso.
