Ainaro (Portuguese: Município Ainaro, Tetum: Munisípiu Ainaru) is one of 13 municipalities of East Timor, in the southwest part of the country. It has a population of 59,175 (census 2010) and an area of 804 km². Its capital is the city of Ainaro, a small mountain town.
Ainaro has a great abundance of rivers and fertile terrain for agriculture. It has a coastal area, on the Timor Sea, but also mountainous zones, including the highest point in East Timor, Mount Ramelau (2,960 m), also known as Tatamailau, which lies near the border with Ermera.
The borders of the municipality are identical to that of the same in Portuguese Timor, with the following exceptions: during the Indonesian occupation, the then subdistrict of Turiscai became part of Manufahi from Ainaro, and the then subdistrict of Hato-Udo became part of Ainaro in exchange. The then subdistrict of Mape-Zumalai became part of Cova Lima in 2003.
Ainaro played an important role during the brutal Indonesian occupation of East Timor, providing shelter for the mountain-based guerrilla resistance army. Former guerrilla leader and current President Xanana Gusmão spent many years directing the resistance from Ainaro.
