Jan Mankes (15 August 1889, Meppel, Drenthe – 23 April 1920, Eerbeek) was a Dutch painter. He produced around 200 paintings, 100 drawings and 50 prints before dying of tuberculosis at the age of 30. His restrained, detailed work ranged from self-portraits to landscapes and studies of birds and animals. His work is now exhibited in his native Netherlands in the Museum of Modern Art Arnhem, Museum Belvédère Heerenveen and Museum MORE Gorssel.
