Kotagede is a city district (kemantren) and a historic neighborhood in Yogyakarta, Special Region of Yogyakarta, Indonesia. Kotagede contains the remains of the first capital of Mataram Sultanate, established in the 16th century. Some of the remains of the old Kotagede are remains of the palace, the royal cemetery, the royal mosque, and defensive walls and moats. Kotagede is well known internationally for its silver crafting.

Plered was the location of the palace of Amangkurat I of Mataram (1645–1677). Amangkurat moved the capital there from the nearby Karta in 1647. During the Trunajaya rebellion, the capital was occupied and sacked by the rebels, and Amangkurat died during the retreat from the capital. His son and successor Amangkurat II later moved the capital to Kartasura. It was twice occupied by Diponegoro, during the Java War (1825–1830) between his forces and the Dutch. The Dutch assaulted the walled complex in June 1826, which was Diponegoro's first major defeat in the war.
