Marieval ("Valley of Mary" in French) is a hamlet in Saskatchewan.
The hamlet was the location of the former Marieval Indian residential school, which was part of the Canadian Indian residential school system. In June 2021 at least 600 and up to 751 unmarked graves were found at what is now the community gravesite, located near the site of the former school and formerly overseen by the Roman Catholic Church, the most found in Canada to date. Chief Cadmus Delorme says these graves may have had marks in 1960, but the headstones were removed by representatives of the Catholic Church and today they are unmarked. Delorme notes that "removing headstones is a crime in this country" and also says "We cannot affirm that they are all children but there are oral stories that there are adults in this gravesite as well. Because it was the Roman Catholic church that overseen this gravesite, some may have went to the church and from our local towns and they could have been buried here as well."
