Hawaii Kai is a largely residential area located in the City & County of Honolulu, in the East Honolulu CDP on the island of Oʻahu. It is the largest of several communities at the eastern end of the island. The area was largely developed by Henry J. Kaiser around the ancient Maunalua fishpond and wetlands area known as Kuapā (meaning "fishpond wall").

The Kalama Valley is a community within the town of Hawaiʻi Kai located on the eastern coast of the island of Oʻahu. It features a shopping center, a public park and basketball facilities, and predominately single-family, relatively high-priced housing, due to its location in Hawaiʻi Kai. The Kamehame Ridge is also most famous for its popular hike, known locally as “Dead Man’s Catwalk”.
