Tukuyu, known as Neu Langenburg during the German's colonial rule, is a hillside town that lies about 36 miles (58 km) south of the city of Mbeya, at an elevation of around 5,000 ft (1,500 m) in the highland Rungwe District of southern Tanzania, East Africa. Tukuyu has a moderate to cool temperature ranging from 10 °C in May and June to mid 20 °C in around November. The town and the surrounding areas are green all year round due to the almost year-round convectional rains resulting from Lake Nyasa. Tukuyu is divided into several wards include; Kawetere, Msasani, Bulyaga and Bagamoyo.

The local language is Nyakyusa, together with the national language Swahili. Secondary and college education is done in the English language. The people are the Nyakyusa, although localised groups give themselves different local names, such as the Waandali from the surrounding Ileje mountains. There are also intermarriages with the Kinga, Wabena and Kisii tribes from the Livingstone mountain ranges.

The Nyakyusa tribe which dominates the whole of Rungwe and Kyela Districts, these districts can also be found in the Northern Part of Malawi.
