Sungailiat, also known as Liet-kong in Hakka, is a town and district (kecamatan) of Bangka Regency, in the Bangka-Belitung province of Indonesia.

The town is located on the eastern coast of the island, about 30 kilometres north of Pangkal Pinang, to which it is connected by a paved road.

The name Sungailiat is believed to derive from a toponym, using what locals call their place with an abundance of river.

However, the original river of Sungai Lihat has been lost due to large-scale tin mining.

As with many settlements in the province, the economy is heavily affected by the mining and processing of tin, very abundant in the area.

The locals are also engaged in fisheries and agriculture, cultivating rubber trees, pepper, and, to a lesser degree, palm oil.

Small enterprises also exist, processing raw products from the aforementioned industries into light foods, like pork and fishes.

The management uses an open dumping and composting system with an average volume of 49 m3 of organic waste per day.
