The North American Discus Association (NADA) is a 501(c)(3) nonprofit organization established in 2004. It brings together discus enthusiasts, hobbyists, and breeders who work to advance the discus-keeping hobby through education and improvements in the quality of fish kept and bred. NADA aims to inform the general public, welcome new members, share practical knowledge, and promote discus through fish shows.

The association offers educational resources covering discus care, including water management, illness, breeding, varieties, and wild discus. Its website also features articles, membership information, organizational history, and details about NADA projects. Shows are a central part of its activities: in 2025, NADA held its first virtual discus show, with entries judged across categories including solids, albino, spotted, striated, and open or unclassified. The organization also invites members and supporters to contribute through donations and sponsorships, which help sustain its nonprofit work. NADA connects with its community through its website and Facebook, providing ways to learn, participate, and support the discus hobby.
