Kieta is a port town located on the eastern coast of the island of Bougainville in Papua New Guinea, near the township of Arawa. After extensive destruction during the 1990 Civil Uprising on Bougainville, Kieta has few inhabitants now, and is known mainly for its transport connections (wharf and airfield).
On 17 May 1885, agreements were made between Germany and the United Kingdom over the islands of Bougainville and Buka in the area of the German sphere of interest. On 20 September 1905 a station was built with a post office and customs. Since 1902, there was a Catholic mission station in Kieta.
