Assinins is a small complex in Assinins, Michigan. It was originally built as a mission by Bishop Frederick Baraga, who founded the site in 1843. He was invited by the local chief, Edward Assinins, whose name was used for the site.

It is said that Baraga and his people did not have a hard time in establishing themselves in the area. In fact, they seem to have had an excellent relationship with the local leader as Chief Assinins was also the first individual that was baptized on the site. The chief allowed the mission to build the Old

St. Joseph Orphanage and School in 1860 that operated until the mid 1900s. The area was also returned to the Chippewa Indians after the Civil War.
Today, the Assinins complex functions as the Keweenaw Bay Indian Tribal Center.
