Notre-Dame-de-Lourdes is a geographic parish in Madawaska County, New Brunswick, Canada.

For governance purposes, the parish is divided between the town of Vallée-des-Rivières in the southwest and the Northwest rural district in the northeast, both of which are members of the Northwest Regional Service Commission.

Before the 2023 governance reforms, the entire parish formed the local service district of the parish of Notre-Dame-de-Lourdes.

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

Notre-Dame-de-Lourdes was erected in 1922 from Sainte-Anne Parish.

In 1946 Notre-Dame-de-Lourdes was affected by the major reorganisation of Madawaska County parish boundaries.
