Josse Impens was a Belgian painter known for his interior scenes, genre scenes, portraits and nudes. He painted a number of scenes of artists and women in artist studios seen from the back. He also painted some city views.

Impens was born in Brussels. He studied in his home town at the Académie Royale des Beaux-Arts where Jean-François Portaels was one of his teachers. Portaels was a prominent painter of genre scenes, biblical stories, landscapes, portraits and Orientalist subjects and the founder of the Belgian Orientalist school. Portaels further operated a private art studio in which he trained the next generation of Belgian painters. Impens was also one of the students in Portaels' private studio.

Impens exhibited works at the salons in Brussels (1891 and 1896) and Munich (1891 and 1894).

He lived and worked in Schaerbeek where he died in 1905.
