The Pityusic Islands, often referenced simply as the Pityuses (Catalan: Pitiüses [pitiˈuzəs], Spanish: Pitiusas; from the Greek πιτύα pitýa, pine tree), or commonly but informally (and ambiguously) as the Pine Islands, is the name given collectively to the Balearic islands of Ibiza (Catalan: Eivissa), Formentera, S'Espalmador and other small islets in the Mediterranean Sea.
