贝街（英语：Bay Street）是加拿大安大略省多伦多市中心一条主要南北向街道，南起安大略湖湖滨的皇后码头路（Queen's Quay），北至戴云宝路（Davenport Road）。贝街座落多伦多市金融区的心脏地带，而自多伦多于20世纪70年代取代蒙特娄成为加拿大金融中心后，「贝街」一词亦成为加国金融业的转喻。仲量联行于2011年公布的一项房地产调查显示，贝街沿线办公室每平方呎全年租金为52.09美元，为全加拿大最高及美加合计第九高。

欧洲人刚到现多伦多市定居时，现贝街介乎皇后西街和湖滨的路段时有熊只出没，因此这条街道的本名为熊街（Bear Street），到了1800年左右则因为此街的南端为安大略湖一个湖湾所在而改为现称。

Bay Street is a major thoroughfare in Downtown Toronto. It is the centre of Toronto's Financial District and is often used by metonymy to refer to Canada's financial industry since succeeding Montreal's St. James Street in that role in the 1970s.

Bay Street begins at Queens Quay (Toronto Harbour) in the south and ends at Davenport Road in the north. The original section of Bay Street ran only as far north as Queen Street West. Sections north of Queen Street were renamed Bay Street as several other streets were consolidated and several gaps filled in to create a new thoroughfare in the 1920s. The largest of these streets, Terauley Street, ran from Queen Street West to Grenville Street. At these two points, there is a curve in Bay Street.
