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.

The 2011 electoral results in this riding were challenged in court on the grounds that there were "irregularities, fraud or corrupt or illegal practices that affected the result of the election".

The seat's present federal MP is Pauline Rochefort, a member of the Liberal Party.

Despite the fact that 99% of this riding stayed the same after the 2012 redistribution, based on the results of the 2011 election — in which Aspin defeated Rota by a margin of just 18 votes — the minor boundary changes were enough to make the seat a notional Liberal riding. The riding lost two Conservative voting areas in the north (Hudson Township and Harris Township) while gaining the Nipissing 10 Indian Reserve, where the Tories finished third.
