Joseph Bourret (10 June 1802 – 5 March 1859) was a 19th-century Canadian lawyer, banker and politician.

Bourret was the third (1842-1844) and sixth (1847-1849) mayor of Montreal, Quebec, and served as minister of public works in the Lafontaine-Baldwin government.

Bourret was supported by Louis-Hippolyte Lafontaine because as a moderate, he was acceptable to the rich Anglo-Saxons who formed the majority of the Montreal electorate.

While Lafontaine and Bourret supported responsible government, they provided a more moderate option than the radicals that led the Rebellions of 1837.

The bank was established to serve working-class Quebecers and had the strong support of the Roman Catholic Church.
