The House of Frankopan (Croatian: Frankopani, Frankapani; Italian: Frangipani, Hungarian: Frangepán. Latin: Frangepanus/Francopanus), was a Croatian noble family, whose members were among the great landowner magnates and high officers of the Kingdom of Hungary–Croatia.

The Frankopan family was one of the leading Croatian aristocratic families which dates back to the 12th century. Along with the Zrinski family it had, in Croatian and Hungarian history, ranked high in terms of importance by virtue of power, wealth, fame, glory and role in Croatia's public life. Some scholars consider them (according family's tradition) to be closely connected with the Roman patrician Frangipani family. The Frangipani were a Roman princely family which claimed descent from a Roman plebeian family of Anicii. The family allegedly took the name Frangipani in the 8th century. In 837 four brothers of the Frangipani family left Rome: Michele chose Venice as his domicile and Nicolò Dalmatia and Slavonia. The descendants of Michele obtained the island of Krk from the Venetians. The Croatian family proclaimed themselves "Frankopan" in 1430, and are first mentioned in Croatian documents in 1133 when Dujam of Krk is recorded as ruler and lord of the island of Krk and of areas of Dalmatia. Around 1200 the family owned wide areas on the mainland, including the Castle of Ribnik, near Karlovac.
