Sungai Selan is a district (kecamatan) of Central Bangka Regency, in the Bangka-Belitung province of Indonesia.

Sungai Selan was the initial point for the spread of Catholicism into Bangka, originating from Catholic Chinese physician Tsjen On Ngie (1795–1871) who moved from Penang into Sungai Selan in 1830, and his house gradually became a makeshift chapel with statues and prayer rooms.

By 1853, a resident priest had been assigned to the area, and although the number of Catholics fluctuated (recorded at 379 in 1967, mainly Chinese migrant workers who often returned to China), a Capuchin friar was assigned to Sungai Selan in 1912, until 1918 when shifts in the tin mining industry resulted in a relocation of the mission to Pangkal Pinang.

[7] Agriculture and tin mining comprises the largest sources of employment in the district, with oil palm and black pepper being major commodities.

[8] The port serves speedboats crossing from South Sumatra,[9] and handles around 200 tons of cargo daily.
