Ottawa (City of) was a federal electoral district in the province of Ontario, Canada, that was represented in the House of Commons of Canada from 1867 to 1935.
It was created by the British North America Act of 1867. It consisted of the city of Ottawa. After 1872, two MPs represented this electoral district at any one time.
In 1892, it was redefined to exclude the New Edinburgh district of the city. In 1903, it was redefined as the city of Ottawa, excluding Rideau Ward. In 1914, it was redefined to exclude Hintonburgh (sic), Bayswater and Mechanicsville neighbourhoods as well as Rideau Ward. It continued to return two members.
In 1924, it was redefined as the city of Ottawa, excluding Rideau Ward and that part of the city lying west of a line beginning at the intersection of the Rideau Canal with the Canadian Pacific Railway in the south, and following the railway, Somerset Street, Bayswater Avenue, Bayview Road and Mason Street, to the Ottawa River.
The electoral district was abolished in 1933 when it was divided into Ottawa West and Ottawa East ridings.
