Bang Yi Ruea (Thai: บางยี่เรือ, pronounced [bāːŋ jîː rɯ̄a̯]) is a khwaeng (sub-district) in Thon Buri district, Thonburi side of Bangkok.

This area was used as a hiding place for firing to the Burmese army's boats.

Hence the name "Bang Ying Ruea" (บังยิงเรือ), literally means "hiding to fire a boat", and wrong pronunciation to "Bang Yi Ruea" finally.

Bang Yi Ruea was an amphoe (อำเภอ; district) under the administration of Thonburi province named "Amphoe Ratchakhrue" (อำเภอราชคฤห์) and changed its name to Bang Yi Ruea in 1916.

Later on, in 1939, amphoe Bang Yi Ruea was renamed to Amphoe Thon Buri to commemorate King Taksin, and it has been modified several times until the sub-district status as today.
