Matej Sternen (20 September 1870 – 28 June 1949) was a leading Slovene Impressionist painter.
Sternen was born in the Carniolan village of Verd—now part of the Municipality of Vrhnika, Slovenia, then part of the Austro-Hungarian Empire—and baptized Matthæus Strnen. He attended the secondary school in Krško and attended technical school in Graz between 1888 and 1891. After finishing the school in Graz, he enrolled at the Academy of Fine Arts in Vienna. In 1897 he left Vienna for Munich, where he studied at Anton Ažbe's private art school. He lived and worked in the Bavarian capital until Ažbe's death in 1905.
