Halekulani (var. Halekūlani) is an oceanfront luxury hotel located on Waikiki Beach in Honolulu, Hawaii. Built in 1984, it contains 453 rooms in five buildings on 5 acres (20,000 m) of property.

The name Halekūlani is a combination of Hawaiian words (hale + kū + lani) meaning "House Befitting Heaven". It is commonly spelled "Halekulani" without the macron (kahakō).

There are three restaurants on the property – House Without a Key, Orchids, and La Mer. It is also the home of SpaHalekulani and the Lewers Lounge.

The hotel is a member of both The Leading Hotels of the World and Imperial Hotel, Ltd., marketing and trade associations geared toward luxury hotels.

Halekulani has received numerous awards, including a World's Best 2005 award from Travel & Leisure magazine. It received Four Stars from Mobil Travel Guide and a AAA Four Diamonds rating.

The hotel is currently owned and operated by the Japanese company Mitsui Fudosan. It brought luxury hospitality executive Peter Shaindlin to Hawaii as CEO of the Halekulani Corporation, overseeing the hotel. The hotel's boutique sister property, Waikiki Parc, is located across the street.

The current structure replaced an original building designed by C.W. Dickey, and built in 1931.

In 1883, businessman Robert Lewers built a two-story house on the site of the modern hotel's main building. In 1907, Lewers leased the property to journalist Edward Irwin, who converted it to a hotel called the Hau Tree. It was purchased in 1917 by Juliet and Clifford Kimball, who established it as Halekulani. The Kimballs enlarged the resort over the years, purchasing a neighboring plot of land and adding additional buildings. After their deaths, their heirs sold the hotel to the Norton Clapp family in 1962 for $4.2 million. In 1978, the Clapps announced their intention to replace the aging collection of structures with a modern luxury hotel. On January 15, 1981 the hotel was purchased by Mitsui Fudosan USA and incorporated as the Halekulani Corporation, a U.S. based company. The current 453-room hotel structure opened in 1984.

The original Halekulani was a plain residential hotel, more an informal grouping of simple bungalows on simple landscaping, offering inexpensive, unpretentious accommodations, with simple food. Later it grew into a more conventional hotel with numerous buildings containing several rooms each and two well known restaurants; one being the House Without a Key made famous by the Earl Derr Biggers novel of the same name. The other was the Coral Tree Lanai, known for its gracious seaside service. The low density on the extensive grounds made it an attractive investment for expansion with new structures.
