Bang Khen (th|บางเขน, pronounced as /th/) is one of the 50 districts (khet) of Bangkok, Thailand. It is bounded by other Bangkok districts (from north clockwise): Sai Mai, Khlong Sam Wa, Khan Na Yao, Bueng Kum, Lat Phrao, Chatuchak, Lak Si, and Don Mueang.
Bang Khen was established as an amphoe (district) of Phra Nakhon province in 1897. The district occupied a vast plain called Thung Bang Khen (ทุ่งบางเขน; 'Bang Khen Field') in north Bangkok. Farms dominated its landscape.[2] In October 1933, the district was a battleground in the "Boworadet rebellion" contested by the army of Prince Boworadet and government troop.[3]
Its name "Bang Khen" is said to be distorted from the word Bang Ken (บางเข็น; 'Place of Push'). It originated from a folk tale titled "Legend of Lord Uthong" (ตำนานท้าวอู่ทอง) when a gold tanker of Lord Uthong (not King Uthong of Ayutthaya) ran aground in a local canal. Therefore, having to push [''ken'' in Thai] a tanker to pass through with tangle.[4]
In 1972, Thonburi and Phra Nakhon Provinces were combined and called Krung Thep Maha Nakhon. Administrative units within the capital were renamed "districts" (khet) and "sub-district" (khwaeng), replacing "amphoe" and "tambon" respectively. Bang Khen became a district in the newly combined province. At that time it had eight sub-districts.
Bang Khen was once a very large district, but has been reduced in size after several modifications to district boundaries. In 1989, western and southwestern portions were split off to create Don Mueang district and Chatuchak district respectively. In 1997, a northern portion of Bang Khen was split off to create Sai Mai district, but in the same reorganization Bang Khen received Mu 8-10 of Chorakhe Bua subdistrict from Lat Phrao district.thumb|right|Anusawari Lak Si, aka Constitutional Protection Monument, a monument of Boworadet rebellion the Thai Army's 11th Infantry Division occupies 3000lk=inNaNlk=in of land in Bang Khen.[5]
