Louis-Joseph d'Herbomez (January 17, 1822 – June 3, 1890) was a Canadian Roman Catholic priest, Vicar Apostolic of British Columbia, and Titular Bishop of Miletopolis from 1863 to 1890.

In 1849, Louis-Joseph d'Herbomez became a Roman Catholic priest of Oblates of Mary Immaculate (OMI).

Louis-Joseph d'Herbomez died on June 3, 1890, in New Westminster, British Columbia, Canada.

Named the Grotto of Our Lady of Lourdes, it was an eight-sided, domed structure with detachable walls, around which assembled parishioners, most of them First Nations people, would assemble for mass and celebrations, and it was the focus of an annual Passion Play, conducted in the Chinook Jargon, held on the mission grounds.

Renovated in 1954 after years of disuse and disrepair, it was nonetheless demolished in 1965 along with the other older buildings of the mission, due to the construction of the newer St. Mary's Indian Residential School, successor to the original St. Mary's Mission.
