Nipissing—Timiskaming is a federal electoral district in Ontario, Canada, that has been represented in the House of Commons of Canada since 2004. The riding was formed by the amalgamation of the former Nipissing riding with the southeastern portion of the former Timiskaming—Cochrane riding. This riding lost small portions of territory to Timmins-James Bay and gained a small portion from Nickel Belt during the 2012 electoral redistribution.
