Kahikolu Church, Stone church in Honaunau-Napoopoo, Hawaii, US

Kahikolu Church is a stone church about 57 by 62 feet with walls 35 inches thick, built on the site of the earlier Kealakekua Church. Its width became the new building's length, and a bell donated by William E. Dodge of New York was installed. The church could hold about 1,200 people.

English missionary William Ellis proposed Kaʻawaloa as a mission site in 1823, and Kapiʻolani had a thatched church built there in 1824. Cochran Forbes moved the mission to Kepulu in 1839 and finished a stone and coral-lime Kealakekua Church in 1841, abandoned by 1845. John Davis Paris arrived in 1852, found it in ruins, and built Kahikolu on the same site from 1852 to 1855, with a bell donated by William E. Dodge of New York.

The name Kahikolu means 'three in one' in Hawaiian, referencing the Holy Trinity and marking this place as the third church building at this location. The simple stone structure reflects the early Christian settlement period in this coastal area.

The church stands at 82-5931 Napo'opo'o Road in Captain Cook, just inland from Nāpo'opo'o on the south side of Kealakekua Bay. Sunday services begin at 9:30 am, with Sunday School at 8:30. The building reopened for use in 1999, so check current arrangements with the congregation before visiting.

Henry Ōpūkahaʻia, a Big Island native who sailed to New England in 1809 and studied at Yale, died of typhus in Cornwall in 1818 at 26. His family brought his body home, and on August 15, 1993 it was laid in a vault facing the sea at Kahikolu. Hawaii's churches mark the third Sunday in February in his honor.
