Marius Hugh Louis Wilhelm "Max" Blokzijl[a] (20 December 1884 – 16 March 1946) was a Dutch singer and journalist.

After the German occupation of the Netherlands, Blokzijl was sentenced to death and executed for his collaboration with Nazi Germany.

[2] Blokzijl settled in Berlin in 1918, working for the German press until 1940, while also serving as president of the Niederländischer Bund in Deutschland.

[2] In February 1941, the NSB forcibly replaced Hendrikus Colijn as editor of the Protestant newspaper De Standaard with Blokzijl, who held the title of General Secretary for Press Affairs for the party.

[3] In fact Blokzijl's role was much greater than his title implied as he was actually effective head of the press in the Netherlands.
