The Grandmaster's Palace (Maltese: Il-Palazz tal-Granmastru), officially known as The Palace (Maltese: Il-Palazz), is a palace in Valletta, Malta. It was built between the 16th and 18th centuries as the palace of the Grand Master of the Order of St. John, who ruled Malta from 1530 to 1798, and was also known as the Magisterial Palace (Maltese: Palazz Magisterjali). When the knights were expelled by Napoleonic France, it became the National Palace. During the period of British rule beginning in 1800, it was the Governor's Palace (Maltese: Palazz tal-Gvernatur).

The palace became a British royal residence with various governors representing the monarchy and the queen, and with the royal family itself. As an official royal residence it was often used by British sovereigns for major events during their stay in Malta.

The Palace currently houses the Office of the President of Malta. It was also the seat of the Parliament of Malta from 1921 to 2015. Parts of the building, namely the Palace State Rooms and the Palace Armoury are open to the public as a museum run by Heritage Malta. The building undertook a major restoration project which was then inaugurated on 12 January 2024.

The Throne Room (Maltese: Is-Sala tat-Tron), originally known as the Grand Council Hall (Maltese: Is-Sala tal-Gran Kunsill, Italian: Sala del Maggior Consiglio) was built during the reign of Grandmaster Jean de la Cassière. It was used by successive Grandmasters to host ambassadors and visiting high ranking dignitaries. During the British administration it became known as the Hall of Saint Michael and Saint George after the Order of St Michael and St George which was founded in 1818 in Malta and the Ionian Islands. It is currently used for state functions held by the President of Malta.

A large hall at the rear of the palace was used as an armoury from 1604 onwards. The arms collection in the Palace Armoury is regarded as one of "the most valuable historic monuments of European culture", despite retaining only a fraction of its original size. The armoury includes many suits of armour, cannons, firearms, swords, and other weapons, including the personal armour of some Grand Masters such as Alof de Wignacourt, and Ottoman weapons captured during the Great Siege of Malta in 1565
