The National Association of Neonatal Nurses (NANN) is a professional organization for neonatal nurses in the United States.

NANN was founded in 1984 by five neonatal nurses: Patricia Johnson, Linda Bellig, Tracy Karp, Charles Rait and Donna Lee Loper.

This mission is achieved through professional, peer-reviewed publications (Advances in Neonatal Care), educational conferences, and offering books and other materials to neonatal health care professionals.

NANN supported the Newborn Screening Saves Lives Reauthorization Act of 2013 (H.R.

1281; 113th Congress), a bill that would amend the Public Health Service Act to reauthorize grant programs and other initiatives to promote expanded screening of newborns and children for heritable disorders.
