Saint-Joseph is a geographic parish in Madawaska County, New Brunswick, Canada.

For governance purposes it is divided between the city of Edmundston and the Northwest rural district, both members of the Northwest Regional Service Commission (NWRSC). Before the 2023 governance reforms, the local service district of the parish of Saint-Joseph shared the parish's boundaries.

Saint-Joseph bisects Madawaska and Saint-Jacques Parishes, the only area in the province where parishes are discontiguous.

The parish probably takes its name from the Roman Catholic ecclesiastical parish.

Saint-Joseph was erected in 1930 from Madawaska and Saint-Jacques Parishes; the name was spelt without a hyphen.

Saint-Joseph was affected by the major reorganisation of Madawaska County parish boundaries.

In 1973 the hyphen was added to the legal name of the parish.
