Semarapura is a town that serves as the administrative capital of the Klungkung Regency in Bali, Indonesia.

Locally referred to as 'Puri Agung Semarapura' or the Royal Palace of Semarapura after the name of the town, the palace shares the same location as the unmissable and more popular Kerta Gosa or the 'Hall of Justice' complex, which lies just northeast of the palatial compound.

Also around the complex is the Klungkung Regency cultural hall, as well as the Kerta Gosa Museum.

The Klungkung Palace grounds date back to the 17th century and are a silent witness to much of the history of East Bali, including the Dutch colonial intervention in 1908, which led to the fall of the kingdom and the deaths of most of the royal family Nyoman Gunarsa Museum, locally referred to as Museum Seni Lukis Klasik, is the namesake private gallery of the late Balinese maestro, Nyoman Gunarsa.

Semarapura has a tropical rainforest climate (Af) with moderate to heavy rainfall year-round.
