Joseph La Rocque, also spelled Larocque, (28 August 1808 – 18 November 1887) was a Canadian Roman Catholic priest, professor, and bishop.

[1] In 1849, La Rocque became canon at Saint-Jacques Cathedral (Montreal), and in 1849 editor of the diocese's Mélanges religieux (Religious Miscellany),[2] until September 1851 when François-Magloire Derome took over.

Canon La Rocque became spiritual director of the nuns of Notre-Dame de Charité du Bon-Pasteur and the Sisters of Charity of Providence.

During his tenure as bishop, La Rocque helped Catherine Aurelia Caouette found the congregation of the Sœurs Adoratrices du Précieux-Sang, and wrote the community's constitution.

As titular Bishop of Germanicopolis and vicar-general, he remained in his diocese, at the monastery of the Sisters of the Precious Blood (a community which honored him as its founder), until his death on 18 November, 1887, at the age of seventy-nine.
