Waikīkī is a neighborhood of Honolulu, in the City and County of Honolulu, on the south shore of the island of Oʻahu, in Hawaii. Waikīkī Beach is the shoreline fronting Waikīkī.

Waikīkī is home to public places including Kapiʻolani Park, Fort de Russy Military Reservation, Kahanamoku Lagoon, Kūhiō Beach Park, and Ala Wai Harbor.

The area was a retreat for Hawaiian royalty in the 1800s who enjoyed surfing there on early forms of longboards.

A few small hotels opened in the 1880s. In 1893, Greek-American George Lycurgus leased the guest house of Allen Herbert and renamed it the "Sans Souci" (French for "without care") creating one of the first beach resorts. Later that year Robert Louis Stevenson stayed at the resort; subsequently it became a popular destination for tourists from the mainland.

Today, the area is filled with hotels like the Hilton Hawaiian Village, the Halekulani hotel, the Hyatt Regency Waikīkī, the Sheraton Waikīkī, and historic hotels dating back to the early 20th century (such as the Moana Surfrider Hotel and the Royal Hawaiian Hotel). The beach hosts many events a year, including surf competitions, outdoor performances, hula dancing and outrigger canoe races.
