Bang Khla (Thai: บางคล้า, pronounced [bāːŋ kʰláː]) is a district (amphoe) of Chachoengsao province, central Thailand.

Its history dates back to the late Ayutthaya period. Shortly before Ayutthaya's second fall (1766), Bang Khla used to be a place where Phraya Tak (later King Taksin) troops passed and stay overnight.

In the era before the reign of King Rama III of the early Rattanakosin period, Bang Khla used to be the center of Chachoengsao, before the town retreated to the present place.

The name "Bang Khla" roughly translated "place of Khla", Khla is a type of mangrove plant (Calathea) that abounds along the banks of the Bang Pakong River that flows in the past. In addition, according to Sujit Wongthes, an independent historian. Bang Khla used to be informally known as "Rong Khlao" (โรงเหล้า, "liquor factory") because it was home to several breweries.

Bang Khla district was officially established in 1901. The district office was in Wat Mai Bang Khla, and in 2019 in Ban Suan Subdistrict. Bang Khla is the name of the village Ban Bang Khla, which is on the khlong ('canal') Bang Khla. As the district office was not in the center of the district area, the government moved it to Tao Sura, five kilometres from the old site. Later they changed the name of the tambon to Bang Khla to match the district name.

Bang Khla is also known for mangos. It is also the origin of jasmine rice as well (from the change of administrative area, the origin of jasmine rice became the area in neighbouring Ban Pho district today).

Neighbouring districts are (from the east clockwise): Ratchasan, Plaeng Yao, Ban Pho, Mueang Chachoengsao, Khlong Khuean of Chachoengsao Province; and Ban Sang of Prachinburi province.

The important water resource is the Bang Pakong River.

Bang Khla is divided into nine subdistricts (tambons), which are further subdivided into 56 administrative villages (mubans).
