Kealia Pond National Wildlife Refuge is a coastal salt marsh along the south-central coast of the Hawaiian Island of Maui. The refuge is located between the towns of Kīhei and Māʻalaea, on both sides of North Kihei Road, Route 31. The wetland is also a 691-acre (2.80 km2) bird sanctuary, home to 30 species of waterfowl, shorebirds, and migratory ducks, including the ʻaukuʻu (black-crowned night heron, Nycticorax nycticorax hoactli) and the endangered āeʻo (Hawaiian stilt, Himantopus mexicanus knudseni) and ʻalae kea (Hawaiian coot, Fulica alai). Kealia Pond was selected as a wildlife refuge in 1953, protecting an initial 300 acres (1.2 km2) of land. The refuge joined the National Wildlife Refuge System in 1992.
