The Public Service Alliance of Canada (PSAC; French: Alliance de la Fonction publique du Canada, AFPC) is one of Canada's largest national labour unions. It is the largest union in the Canadian federal public sector. PSAC members work in every province and territory, and also work abroad in embassies and consulates.

Many of PSAC's some 200,000 members work for the federal public service, crown corporations, or agencies as immigration officers, fisheries officers, food inspectors, customs officers, national defence civilian employees, and the like. However, an increasing number of PSAC members work in non-federal sectors: in women's shelters, universities, security agencies and casinos. In Northern Canada, PSAC represents most unionized workers employed in the Yukon, Nunavut and the Northwest Territories.

PSAC is headquartered in Ottawa with 23 regional offices across Canada. PSAC's Ottawa headquarters building, designed in 1968 by Paul Schoeler, is a notable example of modernist architecture in Ottawa.^[2]
