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

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 district office was in Wat Mai Bang Khla, and in 2019 in Ban Suan Subdistrict.

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