The Mississippi River Network (MRN) established the 1 Mississippi campaign to support River Citizens through education, inspiration and opportunities to embrace the Mississippi River. MRN is a coalition of 55 nonprofit organizations and businesses working together to protect the land, water and people of the United States’ greatest River.

1 Mississippi was established in 2009 to organize people dedicated to protecting the Mississippi River into a national constituency of River Citizens. River Citizens live in all 50 states, take simple actions to improve the River and advocate for River protections to local and national decision makers.
