Eivissa or Ibiza is one of the Balearic Islands located in the Mediterranean Sea (38.98° N 1.43° E), belonging to Spain. With Formentera, it is one of the two Pine Islands. Major cities are Ibiza Town, Santa Eulària del Riu and Sant Antoni de Portmany.

The name Ibiza is derived from the Original Arabic word "Yabisah" as for Land or Landward in English. Eivissa is the official Catalan name and the name used by its inhabitants and pronounced [əj'vi.sə]; but the name in Castilian Spanish and many other languages is Ibiza (usually pronounced using the Castilian variation [iˈβ̞i.θa], often manifested by English speakers [ɪˈbi.t͡sa]).

The Island of Ibiza is most famously known for its summer parties, with thousands of people flooding in for the big summer club nights. Famous clubs include Space, Pacha, Privilege (ex Ku), Amnesia, Eden and Es Paradis. They are hosts to parties of international fame such as Cream, Manumission, Fuck Me I'm Famous, etc. It is also home to the 'West End' party district of San Antonio, a rite of passage for many partygoers.

The climate of Ibiza is Mediterranean and has milder winters and slightly cooler summers than Mallorca. The winters are mild with temperatures around 60 degrees Fahrenheit, 15 Celsius and some rain. The hot summer season lasts from June to September inclusive with temperatures regularly reaching 30 degrees, lots of sunshine and very little rain. Frost and snow are very rare.

Eivissa is a very popular tourist destination, especially due to its legendary and at times riotous nightlife centered around two areas: Ibiza Town, the island's capital on the eastern shore and San Antonio to the West. Ibiza Town has become a popular destination for tourists.

There also exists a genre of trance music named for Ibiza dubbed Balearic Beat, similarly to the way Goa trance is named for Goa, India. The style tries to reflect the atmosphere of Ibiza, and listeners often say they can see a Mediterranean sunset when they hear its euphoric, uplifting melodies. The atmosphere is brought on with the use of synthesized string instruments, the sound of waves, mandolins and guitars, and wispy vocals.
