Eugène Schaus (12 May 1901 – 29 March 1978) was a Luxembourgian politician and jurist. Schaus was a leading light in the early days of the Democratic Party, of which he would be President from 1952 until 1959. Schaus held office in a number of governments, under Pierre Dupong and Pierre Werner, over a period of thirty years. He served as the Deputy Prime Minister, a position created especially for Schaus, in Werner's first government. He would serve in this capacity again (1969–1974), as well as holding a number of other high offices.
