Manucoco, also referred to as Gunung Manucoco or Mount Manucoco, is a mountain in the Atauro Island subdistrict of the Dili District of East Timor. It stands near the southern end of Atauro Island, at the western end of Wetar Strait, some 25 km (16 mi) north of Dili, the nation's capital. The rugged topography of the island's highlands is a result of the erosion of uplifted, originally submarine, volcanoes from the Neogene period creating narrow, dissected ridges and steep slopes, with Manucoco forming the highest point. The upper levels of the mountain still carry patches of tropical semi-evergreen mountain forest in sheltered valleys, covering about 40 km2 (15 sq mi). The mountain, along with the whole of Atauro Island, has been identified as an Important Bird Area by BirdLife International because it supports populations of several of Timor’s and Wetar's restricted-range native bird species.

Tatamailau, or Tata Mailau, sometimes referred as Mount Ramelau, is the highest mountain in East Timor and also of Timor island at 2,986 m (9,797 ft). The mountain is located approximately 70 km (43 mi) south of the capital Dili in the district of Ainaro. While East Timor was a Portuguese colony it was called the highest mountain of Portugal in the twentieth century, since the highest mountain of Portugal proper is of a more modest height. The name "Tatamailau" is Mambai-origin, the local language and means "Grandfather of all". "Ramelau" is the name of the massif of the mountain. The Tatamailau is dedicated to the Virgin Mary and the subject of an annual pilgrimage commemorating the Annunciation of the Blessed Virgin Mary, on or around 25 March. There is a three-metre-high statue of the Virgin Mary on the peak, which came from Italy and was erected during Indonesian occupation in 1997.
