About FRIENDS OF THE WAIKIKI AQUARIUM

Friends of the Waikīkī Aquarium (FOWA) is the membership and fundraising organization that supports the Waikīkī Aquarium’s education, research, conservation, and visitor programs. The EIN provided (99-0322295) matches the organization’s federal tax identification as shown on the organization’s own materials and public nonprofit filings, confirming this profile describes the correct entity.

FOWA raises funds, manages membership benefits and events, and partners with the University of Hawaiʻi, NOAA, Sea Grant and local conservation groups to support exhibits, capital projects, and public programming. In the last 2–3 years FOWA has supported the Aquarium’s milestone activities (including the 120th anniversary celebrations), contributed toward infrastructure and exhibit projects (notably work tied to the Edge of Reef redevelopment and new exhibit planning), and continued member-facing programming such as lecture series, concerts, and community outreach.
