(1841-1902) was a Belgian painter.
Born in Werchter, Cornelius van Leemputten is predominantly known for his landscapes with sheep, similar to the style of Charles Jacque. He began his painting career without formal training. He was well-known for his barnyard subjects. Leemputten eventually became a pupil of the Academy of Antwerp, though his style remained primarily self-taught.
Van Leemputten participated across several international exhibitions and received gold medals in Ghent in 1883, Edinburgh in 1886, Port Adelaide in 1887 and in Berlin in 1896. In 1895, he received the Knight of the Order of Leopold (Belgium).
