Halifax is a federal electoral district in Nova Scotia, Canada, is one of a handful of ridings which has been represented continuously (albeit with different boundaries) in the House of Commons since Confederation in 1867.

The riding of Halifax includes the communities of Spryfield, Sambro, Herring Cove, Harrietsfield, Williamswood, Prospect, Purcell's Cove, Armdale, Cowie Hill, Fairmount, Kline Heights, and the peninsula of Halifax.

The electoral district was created at Confederation in 1867. It returned two members until 1968.

The most notable of the riding's MPs was Robert Borden, who was Conservative leader from 1901–1920, and Prime Minister of Canada from 1911-1920. Borden represented the riding from 1896–1904 and again from 1909-1917. Another notable MP was Robert Stanfield, leader of the Progressive Conservative Party from 1967-1976, who represented the riding from 1968-1979.

Halifax was represented by the New Democratic Party from 1997 to 2015, with the Liberal Party coming in second in every election from 2000 to 2015. The riding's boundaries were re-distributed in 2004. Before that date, it comprised the peninsula of Halifax, the community of Fairview, and part of Clayton Park.
