Dominique Mondelet (January 23, 1799 – February 19, 1863) was a lawyer, judge, seigneur and political figure in Lower Canada.
He was born in Saint-Marc-sur-Richelieu, the son of notary Jean-Marie Mondelet, and studied at the Collège de Montréal.
He articled in law with Michael O'Sullivan, was admitted to the bar in 1820 and set up practice in Montreal.
He was elected to the Legislative Assembly of Lower Canada for Montreal County as a moderate Reformer in an 1831 by-election held after the death of Joseph Perrault.
Mondelet was later named to the Special Council that administered the province after the Lower Canada Rebellion.
