The House of Commons (French: Chambre des communes) is a component of the Parliament of Canada, along with the Sovereign (represented by the Governor General) and the Senate. The House of Commons is a democratically elected body, consisting of 308 members, who are known as Members of Parliament (MPs). Members are elected for limited terms, holding office until Parliament is dissolved (a maximum of five years). Each member is elected by, and represents, one of the country's electoral districts, which are colloquially known as ridings.

The House of Commons was established in 1867, when the British North America Act 1867 created the Dominion of Canada, and was modelled on the British House of Commons. The "lower" of the two houses making up the parliament, the House of Commons in practice holds far more power than the upper house, the Senate. Although the approval of both Houses is necessary for legislation, the Senate very rarely rejects bills passed by the Commons (though the Senate does occasionally amend bills). Moreover, the Government of Canada is responsible solely to the House of Commons. The Prime Minister stays in office only as long as he or she retains the support of the Lower House.

It is widely thought that "Commons" is a shortening of the word "commoners". However, the term derives from the Anglo-Norman word communes, referring to the geographic and collective "communities" of their parliamentary representatives and not the third estate, the commonality. Canada remains the only nation besides the United Kingdom to use the name "House of Commons" for the Lower House of Parliament.

The Canadian House of Commons is located in the Centre Block of the Parliament Buildings on Parliament Hill, in Ottawa, Ontario.
