Kraton or Keraton is the Javanese word for a royal palace. Its name is derived from ka-ratu-an which means the residence of ratu. Ratu is the traditional honorific title to refer the "ruler" (king or queen). In Java, the palace of a prince is called puro or dalem. The general word to designate a palace is istana, as in Indonesian and Malay.
Kraton that function as the residence of a royal family include:
- Yogyakarta region
- Kraton Ngayogyakarta Hadiningrat (Palace of Hamengkubuwono I to X).
- Puro Pakualaman (Palace of Pakualam).
- Surakarta (Solo) region
- Cirebon area
The locations of former kraton has been determined by historical records or archaeological efforts. Former kraton include:
- Kraton Ratu Boko, east of Yogyakarta in the Prambanan area. The structure dates from 9th century and is thought to belong to the Sailendra or Mataram Kingdom, however local inhabitants named this site after King Boko, the legendary king in Loro Jongrang folklore.
- Kraton of Majapahit in Trowulan, Mojokerto, the capital of the former Majapahit. Sites such as Pendopo Agung Majapahit are thought to be remnants of the Kraton of Majapahit.
- Kraton Surosowan, Banten, former royal palace of Sultanate of Banten 
- Kraton Kaibon, the former palace of queen mother 
In Yogyakarta and Surakarta region, there is the remnants of Sultanate of Mataram palaces:
- Kota Gede remains of a palace from the 16th century.
- Karta and Plered, there are remains of palaces from the 17th century
- Kraton Kartasura on the outskirt of Surakarta, remains of palace and city wall, also dated from 17th century
The term kraton 'palace' is also used as a way to refer to the court which it houses.
This is especially the case for native Indonesian states where the succession is disputed, giving issue to two or more branches of the dynasty, or even rivaling dynasties, each setting up an alternative court, while competing for the same state, but generally only controlling part of it.
