Jules Joseph, Baron d'Anethan (French pronunciation: [ʒyl ʒozɛf baʁɔ̃ dantɑ̃]; 23 April 1803 – 8 October 1888) was a Belgian Catholic Party politician.

During his term in office, d'Anethan was responsible for directing the Belgian reaction to the Franco-Prussian War.

D'Anethan and the king agreed a programme whereby the King's favoured military reforms—in particular the abolition of Remplacement conscription—would be implemented, along with an agreement not to institute electoral reforms.

D'Anethan was obliged to include in his cabinet ministers who were opposed to the abolition of Remplacement which led to conflicts with the King.

A political crisis following his nomination of Pierre de Decker as governor of Limburg led to the resignation of d'Anethan's government.
