Pine Islands (Catalan Illes Pitiüses) is the name given collectively to the Balearic Islands of Ibiza (Eivissa) and Formentera, in the Mediterranean Ocean.

The islands are situated approximately 100 km southwest of the island of Majorca (Mallorca), and approximately 80 km east of the Spanish mainland (Cabo de la Nao, Alicante, Valencia).

The Pine Islands are sometimes grouped together as part of the Balearic Islands, or else considered separate with the Balearics proper being Majorca and Minorca (Menorca). Politically, they are part of the autonomous community of the Balearic Islands.
