Justus van Effen (21 February 1684 – 18 September 1735) was a Dutch author, who wrote chiefly in French but also made crucial contributions to Dutch literature. A journalist, he imitated The Spectator with the publication of the Dutch-language Hollandsche Spectator. He gained international fame as a writer of French periodicals and a translator from English into French, and he is also recognized as one of the most important Dutch language writers of the 18th century and an influential figure of the Dutch Enlightenment.
