River Ridge is an unincorporated community and census-designated place in Jefferson Parish, Louisiana, United States. It is a suburb of New Orleans. The population was 13,591 in 2020. The land that is now River Ridge was developed by French colonists and their descendants in the late 18th and early 19th centuries for large sugar plantations; these lined the Mississippi River in traditional French long-lot fashion. The plantations had relatively narrow waterfronts, in order to provide water access, and extended deeply back from the river. These plantations were developed by French colonists and their descendants; they depended on the labor of African slaves. Major landowners included members of the Trudeau and Sauve families.
