Wahiawa, Hawaii

Wahiawa is a census-designated place in Honolulu County, Hawaii, United States, on the island of Oahu. It is in the Wahiawa District, on the plateau or "central valley" between the two volcanic mountains that comprise the island. In Hawaiian, wahi a wā means "space of the wa people". The population was 18,658 at the 2020 census.

Lakes and reservoirs are rare in Hawaii, and Wahiawa is unique in being surrounded on three sides by Lake Wilson. The town must be reached by either of two bridges on Kamehameha Highway across the reservoir's narrow north and south arms. Outside of the reservoir, the town used to be surrounded by military bases and agricultural fields, but development is making its way up from the increasingly urbanized southern portion of the central plain.
