Ottawa (County of) () was a federal electoral district in Quebec in the House of Commons of Canada from 1867 to 1892. It was based in the Outaouais region of Quebec, across the Ottawa River from the city of Ottawa, Ontario.

The electoral district was created by the British North America Act, 1867, based on the former electoral district of Ottawa in the Legislative Assembly of the Province of Canada. The district was redistributed into the new electoral districts of Wright and Labelle in 1892.
