Chom Thong (Thai: จอมทอง, in Thai pronounced as /t͡ɕɔ̄ːm tʰɔ̄ːŋ/) is one of the 50 districts (khet) of Bangkok, Thailand. The district is bounded by the districts (clockwise from north) Phasi Charoen, Thon Buri, Rat Burana, Thung Khru, Bang Khun Thian, and Bang Bon.
Chom Thong was included in Bang Khun Thien District until an announcement on November 9, 1989. On 14 October 1997, parts of Bang Pakok sub-district of Rat Burana and parts of Bukkhalo Sub-district of Thon Buri were transferred to Chom Thong during the administrative reform which rearranged the 38 Bangkok districts into 50 districts.
Historically, Chom Thong area is the original residence of King Nangklao (Rama III)'s relatives.[2]
The district, together with Thung Khru, is well known for its tangerines, the Bang Mot tangerine. There is a giant tangerine sculpture at the junction between Rama II Road and Suk Sawat Road where Rama II Road originate. The district is also the home of the Poomjai Garden lychee farm, Bangkok's last lychee plantation.[3]
The district is sub-divided into four sub-districts (khwaeng).
