Hugues Alexandre Sinclair de Rochemont (6 January 1901 – 13 March 1942) was a Dutch fascist and later a collaborator with the Nazis.

Whilst studying Indology at Leiden University, de Rochemont became associated with the rightist professor Gerardus Johannes Petrus Josephus Bolland (1854–1922).

In 1927, he began editing De Bezem (The Broom), a fascist journal aimed at the working classes and continued to publish under this name after 1930, when he split from Haighton.

[1] Having split from Haighton, de Rochemont became associated with Joris Van Severen of Belgium, although most of his time was given over to his work as a civil servant and then as an antiquarian bookseller.

[1] After spells in prison for homosexuality[1] and attempting to assassinate Anton Mussert, de Rochemont volunteered for the Dutch legion of the Waffen-SS and was killed on active duty near Grisi in the Soviet Union.
