Census designated place in Hawaii, United States

Kailua /k//aɪ/'/l//uː//ə/ is a census designated place (CDP) in Honolulu County, Hawaii, United States. It lies in the Koolaupoko District of the island of Oahu on the windward coast at Kailua Bay. It is in the judicial district and the ahupua'a named Ko'olaupoko. It is 12 mile (19 km) northeast of Honolulu – over Nu‘uanu Pali. In the Hawaiian language Kailua means "two seas" or "two currents", a contraction of the words kai (meaning "sea" or "sea water") and elua (meaning "two"); it is so named because of the two former fishponds in the district (Kawainui and Kaelepulu) or the two currents that run through Kailua Bay. Kailua is primarily a residential community, with a centralized commercial district along Kailua Road. The population was 50,000 in 1992. In 2017 census, the population had dropped to 38,000. The population was 40,514 at the 2020 census. Places of note in Kailua include Kailua Beach Park, Kaōhao or Lanikai Beach, Kawainui Marsh, Maunawili Falls, and Marine Corps Base Hawaii. It was home to Barack Obama’s winter White House.

During the reign of King Kākuhihewa and his successors, Kanekapu, Kahoowaha, Kauakahiakahoowaha, and Kualiʻi, Kailua replaced Waikiki as the residential seat of the Oʻahu Rulers (aliʻi nui of Oʻahu). Many ancient temple ruins, such as those at Ulupo Heiau State Historic Site, are in the area. After the Oʻahu army's defeat by King Kamehameha the Great at the Battle of Nuʻuanu in 1795, the political capital and residential seat of the aliʻi nui of Oʻahu was relocated from Kailua to Honolulu.

Kailua Beach is crescent shaped, about 2.5 mile (4 km) long, and ranging between wide. The ocean bottom fronting the beach slopes gently to overhead depths without any coral heads. Light to medium waves support surfing and bodysurfing. The steady trade winds make Kailua Beach a top windsurfing and kitesurfing destination. Robby Naish, first World Champion of windsurfing and Professional Windsurfers Association Hall of Fame inductee, grew up in Kailua. Sea kayaking and stand up paddleboarding to the protected seabird sanctuaries Flat Island and the Nā Mokulua, popularly known as "the Mokes", have become increasingly popular water activities at the beach.

According to the United States Census Bureau, the CDP has an area of , of which is land and (26.62%) is water. A significant portion of the water area is Kawainui Marsh, the largest wetland in the Hawaiian Islands and a Ramsar Convention site.

Kaʻōhao is the earliest known Hawaiian name for the place known as "Lanikai." Kaʻōhao means "the tying" and is derived from an old story in which "two women were tied together here with a loincloth after being beaten in a kōnane game". Kaʻōhao was commercially developed in the 1920s and renamed "Lanikai." It is now an unincorporated community in Kailua on the windward coast at Kailua Bay. Lanikai Beach was rated one of the world's top ten beaches by Sherman's Travel Magazine. The area is known for its white, powder like sandy beach and its hiking trail along the Kaiwa Ridge to the World War II military bunkers commonly known as the "Lanikai Pillboxes". Because of its small community and easy access to its famous beach, Lanikai has one of Hawaii's most expensive real estate markets. It is served by Kailua's zip code, 96734.

Kailua has a tropical savanna climate.

Historically, most tourism on the island of O'ahu has centered around Waikiki and other tourism designated areas. But tourism has also been a major economic force in Kailua, and tourism related jobs have historically made up roughly one third of total employment in Hawaii. The Obama family vacations, as well as coverage from various social media and travel sites, sparked new interest in Kailua as a tourist destination and led to an influx of tourists to Kailua. This influx led to pushback from some Kailua residents, prompting proposals of legislation to limit tourist activity there.

Barack Obama vacationed in Kailua between 2008 and 2012. In 2010, 2011, and 2012, the Obama family stayed in the rented, ocean front house Plantation Estate in the Paradise Point Estates. The house was built by developer Harold Kainalu Long Castle, who also lived there. Obama also took a vacation break in August 2008 at a different house in Kailua, Oahu Lani, during the 2008 United States presidential election.

Although tourism is the primary driver of Kailua's economy, it remains a contentious issue among the town's residents. On several occasions, residents have successfully introduced legislation to discourage tourism in the town. One such example is Bill 41, introduced to the Honolulu City Council in October 2021. In 2022, Honolulu County Mayor Rick Blangiardi signed Bill 41 into law at a press conference held on Kailua beach. The bill places additional limits and restrictions on short term rental units. These include requiring a permit to rent living space in a residential area for less than 90 days, as well as requiring hosting platforms (such as Airbnb) to report all listings in Honolulu County (which includes Kailua town) to the county government. Proponents of Bill 41 expect its passage to dramatically reduce the volume of tourists in Kailua.

The Hawai'i Department of Education operates the public schools. Enchanted Lake, Kaelepulu, Kailua, Kainalu, Keolu, and Maunawili. Kailua Intermediate School, Kalaheo High School, and Kailua High School are also in the CDP. Kailua High and Maunawili Elementary were defined as being in the Maunawili CDP as of the 2000 Census, It became a charter school in 1996, and it received its current name in 2017.
