Sainte-Croix is a town in Port Louis, Mauritius, Africa.
It is most famous for its association with the Roman Catholic beatus Jacques-Désiré Laval, who worked in Sainte-Croix as a missionary from 1841 until his death in 1864. Sainte Croix is the site of Laval's tomb, and is thus a place of pilgrimage for Catholics in Mauritius.
