Cyrille Duquet (31 March 1841—1 December 1922) was a Canadian goldsmith, flutist, and inventor in Quebec. Originally working in the field of clocks and watches, he was also a passionate jewelry collector. In 1883 Duquet made the black rod, a symbol of authority, today preserved at the National Assembly in Quebec City. The main clock of the National Assembly of Quebec bears his signature, as does the clock of Saint-Jean-Baptiste library. A government building located on Charest Boulevard in Quebec City was named in his honor, and a Quebec street bears his name.
