Oecussi-Ambeno (also variously Ocussi, Oekussi, Oekusi, Okusi, Oé-Cusse) is a province of East Timor. It is a coastal exclave on the western part of the island of Timor, separated from the rest of East Timor by West Timor, which is part of Indonesia. The capital of the province is Pante Makasar, also called Ocussi Town.
It was in Pante Makasar that an Indonesian fifth column raised the Indonesian flag and took control of the exclave on 29th November, 1975, a week before the Indonesian invasion of East Timor proper. However, even under Indonesian rule, Oecussi-Ambeno was administered as part of the province of East Timor (Timor Timur in Indonesian), just as it was as part of Portuguese Timor. Consequently, it became part of the independent state of East Timor in 20 May 2002.
