Christoph Dientzenhofer (Czech: Kryštof Dientzenhofer) (born 7 July 1655 in St. Margarethen near Brannenburg, Landkreis Rosenheim - 20 June 1722 in Prague) was a prominent German architect of Bohemian Baroque. He was a member of the famous Dientzenhofer family of architects, and the father of Kilian Ignaz Dientzenhofer.
Among his works are the Church of St. Nicholas (1703–11, later completed by his son) and the Brevnov Monastery (1708–21) in Prague, church of St. Klara in Eger (Cheb) (1708 - 11). Some of his works are difficult to identificate, due to the lack of documentation.
