Adrien-Gabriel Morice (27 August 1859 – 21 April 1939) was a missionary priest belonging to the Oblates of Mary Immaculate.

As a seminarian he was inspired by Father Émile Petitot and set himself the goal of becoming a missionary and explorer in Northwestern Canada.

In 1885 his dreams were realized and he was posted to Fort St. James, the fur trading and missionary center in the Carrier region.

[1][2] Father Morice would have preferred to remain in Fort St. James but in 1904 he was withdrawn by the bishop, who finally paid heed to the complaints of the Hudson's Bay factor.

Father Morice proved unwilling to perform the other duties the bishop assigned him and unable to get along with other priests, so after several years of conflict the Church set him up in a house in Winnipeg where he spent the remainder of his life as a scholar, writing extensively on Carrier language and culture, more general Athabaskan topics, the history of the Roman Catholic church in Western Canada, the history of the French and Métis of the West, and occasional other topics.
