district in Bangkok, Thailand
Khlong San (Thai: คลองสาน, pronounced [kʰlɔ̄ːŋ sǎːn]) is one of the 50 districts (khet) of Bangkok, Thailand. On the west bank of Chao Phraya River, its neighboring districts across the river are (from north clockwise) Phra Nakhon, Samphanthawong, Bang Rak, Sathon, and Bang Kho Laem.

History
Khlong San is one of the oldest districts of Bangkok with a long history. Its name comes from a khlong (คลอง; lit: canal) that runs through the area, called "Khlong San" or "Khlong Prasan". It starts from the Chao Phraya River and flows toward Khlong Somdet Chao Phraya Ong Noi in front of Wat Phichai Yat, connecting with several other canals such as Khlong Wat Thong Thammachat, Khlong Wat Thong Nopphakhun, and Khlong Lat Ya. All of these were waterways passing through the local orchards. The most famous fruit of Khlong San was longkong (a type of langsat). Around 70 to 80 years ago, many of the canals were excavated and replaced by roads such as Lat Ya, Prajadhipok, and Khlong San Roads; now known collectively as Somdet Chao Phraya Road.
Khlong San was called, in chronological order, Amphoe Bang Lamphu Lang (บางลำภูล่าง), Amphoe Buppharam (บุปผาราม), and Amphoe Khlong San (since 1916) when it was part of Thonburi Province.
