The Special Region of Yogyakarta is a province-level special region of Indonesia in southern Java. It is a semi-enclave that is surrounded by on the landward side by Central Java Province to the west, north, and east, but has a long coastline on the Indian Ocean to the south.

Co-ruled by the Yogyakarta Sultanate and the Duchy of Pakualaman, the region is the only officially recognized diarchy within the government of Indonesia. The city of Yogyakarta is a popular tourist destination and cultural center of the region. The Yogyakarta Sultanate was established in 1755 and provided unwavering support for Indonesia's independence during the Indonesian National Revolution (1945–1949). As a first-level division in Indonesia, Yogyakarta is governed by Sultan Hamengkubuwono X as the governor and Duke Paku Alam X as the vice governor. With a land area of just 3,170.65 km, it is the second-smallest province-level entity of Indonesia after Jakarta.

In Javanese, it is pronounced [joɡjaˈkartɔ], and named after the city of Ayodhya in Javanese-Hindu mythology. The Dutch name of the Special Region is Djokjakarta.

The Sultanate has existed in various forms and survived through the rule of the Dutch and the 1942 invasion of the Dutch East Indies by the Japanese Empire. In August 1945 Indonesia's first president, Sukarno proclaimed the independence of the Indonesian Republic, and by September of that year, Sultan Hamengkubuwono IX and Duke Sri Paku Alam VIII had sent letters to Sukarno expressing their support for the newly born nation of Indonesia, in which they acknowledged the Yogyakarta Sultanate as part of the Indonesian Republic. The Sunanate of Surakarta did the same, and both of the Javanese kingdoms were awarded special status as special regions within the Indonesian Republic. However, due to a leftist anti-royalist uprising in Surakarta, the Sunanate of Surakarta lost its special administrative status in 1946 and was absorbed into the province of Central Java.

Yogyakarta's overwhelming support and the Sultan's patriotism were essential in the Indonesian struggle for independence during the Indonesian National Revolution (1945–1949). The city of Yogyakarta became the capital of the Indonesian Republic from January 1946 to December 1948 after the fall of Jakarta to the Dutch. Later, the Dutch also invaded Yogyakarta causing the Indonesian Republic's capital to be transferred again to Bukittinggi in West Sumatra on 19 December 1948. In return for Yogyakarta's support, the declaration of Special Authority over Yogyakarta was granted in full in 1950 and Yogyakarta was given the status of a Special Administrative Region, making Yogyakarta the only region headed by a monarchy in Indonesia.

The Special Region was struck by a 6.3-magnitude earthquake on 27 May 2006, killing 5,782 people, injuring approximately 36,000, and leaving 600,000 people homeless. The region of Bantul suffered the most damage and deaths.

The Special Region is located near the southern coast of Java, surrounded on three sides by the province of Central Java, and with the Indian Ocean on the south side. The population at the 2010 Census was 3,457,491 people, which then increased to 3,668,719 at the 2020 Census; the official estimate for mid-2023 was 3,736,489 (comprising 1,849,540 males and 1,886,950 females). It has an area of 3,170.65 km, making it the second-smallest area of the provinces in Indonesia, after the Jakarta Capital Region. Along with surrounding areas in Central Java, it has some of the highest population densities of Java.

Mount Merapi is located to the immediate north of the city of Yogyakarta and Sleman Regency. It is the most active volcano in Indonesia and has erupted regularly since 1548. It last erupted in October–November 2010, killing and injuring many people and temporarily displacing approximately 100,000 residents.

Indonesia has several geo-heritage sites in the Yogyakarta Special Region. It has been declared by the Geological Agency of the Ministry of Energy and Mineral Resources. The sites consist of nine sites: Eocene limestone in Gamping (Sleman Regency), pillow lava in Berbah (Sleman), pre-historic volcanic sediment in Candi Ijo, Prambanan (Sleman), dunes in Parangtritis Beach (Bantul Regency), Kiskendo cave, and former manganese mining site in Kleripan (Kulonprogo regency), the prehistoric volcano in Nglanggeran (Gunungkidul regency), Wediombo-Siung beaches (Gunungkidul) and Bioturbasi site in Kalingalang (Gunungkidul). The most unusual one is pillow lava in Berbah (Sleman) which is a big, rough black rock that lies on the bank of the narrow Dengkeng River. The prehistoric volcano in Nglanggeran (Gunungkidul Regency) has already been developed as a tourist destination.

According to Act No. 22 of 1948 (which is also the basis of Act No. 3 of 1950 on the formation of DIY), the Head and Vice Head of the Special Region are appointed by the president from the descendants of the ruling family in the region before Indonesian independence with the conditions of "skill, honesty, and loyalty, and keeping in mind the customs of the area." Thus, the Head of the Special Region, until 1988, was automatically held by the reigning Sultan of Yogyakarta, and the Vice Head of the Special Region, until 1998, was automatically held by Prince Paku Alam who was on the throne. The nomenclature of the Governor and Vice Governor of the Special Region has only been used since 1999 with the issuance of Act No. 22 of 1999. Since 2012, the mechanism for filling the positions of Governor and Vice Governor of DIY is regulated by Act No. 13 of 2012 on the Uniqueness of the Special Region of Yogyakarta.

The province has a regional legislature, the Special Region of Yogyakarta Regional House of Representatives, which as of the 2024 election has 55 members. The largest party in the legislature is the Indonesian Democratic Party of Struggle.

The Special Region of Yogyakarta (provincial level) is subdivided into four regencies (kabupaten) and one city (kota), and divided further into districts (kapanewon or kemantren in the city of Yogyakarta) and villages (rural kalurahan or urban kelurahan, doublet); these are listed below, with their areas and their population at the 2000, 2010 and 2020 Censuses, with their present estimates, as of mid-2023.
