Āhualoa is an unincorporated rural area along the Hamakua Coast on the Island of Hawaiʻi, Hawaiʻi County, Hawaii, United States.
The name is believed to mean either "long mound" or "long cloud", in the Hawaiian language. The latter is easily understood from the extremely high rainfall and cloud cover that is typical of the area.
Ahualoa is located at 20°03' North, 155°28' West (20.06, -155.48).
The Old Mamalahoa Highway is the principal road running through Ahualoa. The land is zoned agricultural. A typical lot is 5 acres (2.0 ha) in size. Land use is for residence and small-scale agriculture, including farming, orchards and livestock.
There is no record of Native Hawaiian settlement in the area that is now Āhualoa. It is likely that the Native Hawaiians visited the area for extraction of resources from the ʻōhiʻa lehua-hāpuʻu native forest, but did not live there, as wet forest was not considered a desirable place to live.
