Heʻeia Fishpond (Hawaiian: Loko Iʻa O Heʻeia) is an ancient Hawaiian fishpond located at Heʻeia on the island of Oahu in Hawaii. A walled coastal pond (loko iʻa kuapā), it is the only Hawaiian fishpond fully encircled by a wall (kuapā). Constructed sometime between the early 1200s and early 1400s, it was badly damaged by a 1965 flood and fell into disrepair. A protected area, it was added to the U.S. National Register of Historic Places in 1973. An effort begun in 1988 is underway to restore the fishpond as a fishery, cultural, scientific, and educational resource.
