Jules Destrée (French: [d?st?e]; Marcinelle, 21 August 1863 – Brussels, 3 January 1936) was a Walloon lawyer, cultural critic and socialist politician.
The trials subsequent to the strikes of 1886 determined his commitment within the Belgian Labour Party.
He wrote a Letter to the King in 1912, which is seen as the founding declaration of the Walloon movement.
He is famous for his quote "Il n'y a pas de Belges" (There are no Belgians), pointing to the lack of patriotic feelings in Flemings and Walloons, while pleading for some kind of federal state.
