Moliʻi Fishpond is located southeast of Kamehameha Highway between Kualoa and Johnson Roads, near Kaneohe, on the island of Oahu, in the U.S. state of Hawaii.

The pond encompasses 125 acres (50.59 ha; 0.20 sq mi) The locale is part of the ahupuaa (land division) of Hakipuu.

[2] Ancient Hawaiian fishponds were noted in the 1826 journal of William Ellis, the naturalist on James Cook's third voyage (1776–1779):[3] They [the Hawaiians] have numerous small lakes and ponds, frequently artificial, wherein they breed fish of various kinds, and in tolerable abundance.Moli'i, along with Huilua, Kahaluu and Heʻeia are the only four original Hawaiian fishponds remaining on Oahu.

This system of harvesting ocean catch was unique to Hawaii, and does not exist within other areas of ancient Polynesia.

The craftsmanship applied in constructing the wall is similar to brickwork, in that the gaps and crevices between the stacked stones are plugged with coral and smaller rocks.
