Kapolei (Hawaiian pronunciation: [kəpoˈlej]) is a planned community in the City and County of Honolulu, Hawaiʻi, United States, on the island of Oʻahu.

For statistical purposes, the United States Census Bureau has defined Kapolei as a census-designated place (CDP) within the consolidated city-county of Honolulu.

[7][8] The ancestry was 6.8% German, 4.1% Irish, 2.1% English, 2.0% Portuguese, 1.4% Italian, 1.3% French, 1.3% Sub-Saharan African, 1.0% Polish, 0.5% Norwegian, 0.4% West Indian, and 0.3% Scottish.

In 1986 the ʻEwa Master Plan was revised to include the SUC and the initial residential construction in the Kapolei area began in the late 1980s with commercial developments springing up shortly thereafter.

Other communities in the Kapolei area are the census-designated places of Makakilo and Naval Air Station Barbers Point (now known as Kalaeloa), the industrial area known as Campbell Industrial Park with the state's second largest deepwater port, Barbers Point Harbor,[11] and the resort and marina community of Ko Olina, which includes the Disney Aulani Resort and Ko Olina Golf Club.

A Manawai Street-Kama‘aha Avenue extension was completed in August 2006 and helped to reduce congestion along Kamokila Boulevard and Farrington Highway.

Kapolei Property Development recently contributed $6 million for a joint project with the State Department of Transportation for an additional freeway on-ramp.

Although state and county governments and some of Hawaiʻi's largest companies have significant workplaces in Kapolei, population growth has far out-paced local job creation.

A majority of Kapolei adults work in Honolulu, congesting the main traffic artery, Interstate H-1.

In January 2007, Oʻahu residents saw an increase of 0.5 percent to the general excise tax to help cover the system's construction costs.

Kapolei is located at the southern end of the slopes of the Waiʻanae mountain near the neighborhood of Makakilo with Fort Barrette Road, located along and named for historically important Fort Barrette, connecting Makakilo to Kapolei.

The Interstate H-1 freeway divides more recently developed Kapolei from Makakilo, and traveling eastward on H-1 connects to Waipahu.

In the other direction, the freeway ends about 1 mile (1.6 km) west of Kapolei, merging into Farrington Highway (State Route 93) to Kahe and then to Nānākuli on the Wai‘anae Coast.

Ka Makana Ali‘i, a mall that opened in October 2016, has 1.4 million square feet of retail space and more than a hundred stores.

[25][26] The Federal Bureau of Investigation (FBI) Honolulu field office is in Kapolei at 91-1300 Enterprise Street.

American Renaissance Academy (pre-K through 12) opened as a private school in 2007 in Kalaeloa, Naval Air Station Barbers Point.

[36][37][38] The University of Hawaiʻi – West Oʻahu relocated to Kapolei and opened its new campus in August 2012 at 91-1001 Farrington Highway.
