Halifax, officially known as the Halifax Regional Municipality (HRM), is the capital of the Canadian province of Nova Scotia. It had a population of 403,131 in 2016, with 316,701 in the urban area centred on Halifax Harbour. The regional municipality consists of four former municipalities that were amalgamated in 1996: Halifax, Dartmouth, Bedford, and Halifax County.

Halifax is a major economic centre in Atlantic Canada, with a large concentration of government services and private sector companies. Major employers and economic generators include the Department of National Defence, Dalhousie University, Saint Mary's University, the Halifax Shipyard, various levels of government, and the Port of Halifax. Agriculture, fishing, mining, forestry and natural gas extraction are major resource industries found in the rural areas of the municipality.

Unlike most municipalities with a sizeable metropolitan area, the Halifax Regional Municipality's suburbs have been completely incorporated into the "central" municipality, often by referendum. For example, the community of Spryfield, in the Mainland South area, voted to amalgamate with Halifax in 1968. The most recent amalgamation, which brought the entirety of Halifax County into the Municipality, has created a situation where a large "rural commutershed" area encompasses almost half the municipality's landmass.
