Sky du Mont (born Cayetano Neven du Mont; 20 May 1947) is a German actor.
Sky du Mont's family, who is related to the famous publishers DuMont Schauberg, fled the Nazis in the 1930s to South America. He was born in Argentina as the son of a German and the British Chiquita Neven du Mont (1921–2018). He grew up in England, but came to Germany in 1969, where he studied acting between 1969 and 1972 in Munich.
In Germany, he is well known for playing suave and urbane, sometimes villainous or shady upper-class-characters since the 1970s. He appeared in three of the commercially most successful German film comedies of all time: In Otto – Der Film (1985) as an aristrocratic-looking swindler, as the villain "Santa Maria" in the Western comedy Der Schuh des Manitu (2001) and in Traumschiff Surprise – Periode 1 (2003), where he reprised his role as "Santa Maria" and played a second role as "William der Letzte", an English duke in the Middle Ages.
