Kahaluʻu Bay (/ˌkɑːhəˈluːʔuː/; Hawaiian pronunciation: [ˈkɐhɐˈluʔu]) is a historic district and popular recreation area on the Kona coast of the Big Island of Hawaiʻi.

Since construction of a heiau using the dry-stack masonry technique (uhau humu pohaku) was a major undertaking, it is unusual to find the concentration of about ten that were built on this bay.

Petroglyphs thought to depict the defeat of Kamalalawalu of Maui by Lonoikamakahiki can be viewed at low tide near the temples.

Several kuʻula (sacred stones, said to have been brought from Maui) were monuments to the plentiful fish and Green turtles that are still found in the bay.

Across Aliʻi Drive from the bay are the stone ruins of the original Helani Church built in 1861 by Rev.

As the population moved inland, a new Helani Church was constructed at a higher elevation still used by the congregation today.

The other properties were abandoned, reverting to the holder of the lease in 1995, the investment arm of Kamehameha Schools, which eventually also bought the remaining hotel.

[12] In 2012, Kamehameha Schools announced plans to close and eventually demolish the Keauhou Beach Hotel, and to build a cultural and educational complex on the site.
