Matthias Maris (17 August 1839 – 22 August 1917) was a Dutch painter, etcher and lithographer. He was also known as Matthijs Maris or Thijs. He initially belonged to the Hague School, like his two brothers, Jacob and Willem, but his later works deviated more and more from that school into a unique style influenced by the Pre-Raphaelites. Maris died in London on 22 August 1917, when he was seventy-eight, following a short illness, and was buried there.
