O ganso-do-havaí, ou nēnē, é o ganso endémico do Havaí e a ave nacional do estado. Quase foi extinto no século XX, com apenas 30 aves remanescentes nos anos 1950. Graças a programas de criação em cativeiro intensivos e reintroduções, as populações cresceram para vários milhares. Ao contrário de outros gansos, está adaptado a andar em terreno vulcânico com patas parcialmente dessensoradas. Habita encostas vulcânicas e pastagens do Havaí e outras ilhas.
