Area code 450 is a telephone area code in the Canadian province of Quebec, encompassing the off-island suburbs of Montreal (which is the area code 514 and now 438). The area code is also shared by several small communities in an adjacent part of Ontario: some landline customers in Chute-à-Blondeau (East Hawkesbury), near Pointe-Fortune have 450-451-xxxx numbers from the Rigaud phone exchange. Due to population growth, on 7 May 2009, the CRTC ruled that area code 438 would be extended to overlay both 450 and 514.^[1] However, a later decision revised it and ruled that area code 579 would overlay 450 on its own, effective in August 2010.^[2]

Among the cities served by area code 450 are Longueuil and Laval.

The communities of Boucherville, Varennes, Roussillon, Joliette, Saint-Hyacinthe, Granby, Chambly, Saint-Jean-sur-Richelieu and Vaudreuil-Dorion are also part of this area code.

The main incumbent local exchange carrier in 450 is Bell Canada, plus some independent companies.
