Richard Mortensen (born 23 October 1910 in Copenhagen, Denmark; died 6 January 1993 in Ejby, Denmark) was a Danish painter. Mortensen studied between 1931 and 1932 at the Royal Danish Academy of Art in Copenhagen. Influenced by the works of Wassily Kandinsky, he developed an abstract style. In Copenhagen, Mortensen was joint founder of the "Linien" school of abstract painters. In 1937 he undertook a study trip to Paris, where he met pioneers of surrealism. During the Second World War, Mortensen's works reflected the violence of Europe. He moved to Paris in 1947, remaining there until 1964. Together with Robert Jacobsen, Mortensen became connected to the Galerie Denise Rene in Paris, which became famous for concrete art. His later works are concrete works of art characterised by large, clear, bright colour surfaces.
