The Kingdom of Majorca (also Kingdom of Mallorca) was created by James I of Aragon (Jaume I, "The Conqueror") as a vassal kingdom of the Kingdom of Aragon.

It included the Balearic Islands, Majorca and Minorca, which were conquered from the Moors; the islands of Formentera and Ibiza, more properly known as the Illes Pitiüses, but commonly included as Balearics; the counties of Roussillon and Cerdagne (approximately the present-day Catalunya del Nord ); and the territories James retained in Occitània (the lordship of Montpellier, the viscounty of Carladès and the barony of Omelàs ). On James's death, this kingdom passed to his second son, who reigned under the name James II of Mallorca .

The kings of Mallorca were:

• James (Jaume) I (reigned 1231-1276), creator of the kingdom.
• James (Jaume) II (reigned 1276-1311).
  • Alfonso (Alfons) II (Alfonso III of Aragon, known as el Franc, "the Free"), conquered the island of Majorca in 1285 and Ibiza in 1286 from James II of Majorca, and effectively recovered Minorca from Moorish domination. By the Treaty of Anagni , these island territories were yielded to James II of Aragon. The continental territories of Roussillon, Cerdagne, etc. remained under Alfonso's control.
• Sancho (Sanç) I (reigned 1311-1324).
• James (Jaume) III (reigned 1324-1344).

The kingdom was occupied and annexed in 1344 by Peter IV of Aragon.
