Bang Sue (Thai: บางซื่อ, pronounced [bāːŋ sɯ̂ː]) is one of the 50 districts (khet) of Bangkok, Thailand.

Bang Sue was one of eight outer Bangkok amphoes (districts) established during King Chulalongkorn's reign.

[2] In an administrative reform in 1938, Bang Sue was reduced from an amphoe to a tambon (sub-district), becoming part of Dusit district.

During World War II the bridge was heavily damaged by Allied bombing, since it was being used by the occupying Japanese.

In the 18th century, corresponding to the early Rattanakosin era, used to be a settlement for Annamese (presently known Vietnamese) immigrants.
