Bang Len (Thai: บางเลน, pronounced [bāːŋ lēːn]) is a district (amphoe) in the northern part of Nakhon Pathom province, central Thailand.

Later the government moved the central district to Tambon Bang Pla on the west bank of the Tha Chin.

In 1939 the district was again renamed and received its current name Bang Len.

The 20 billion baht airport would occupy 3,500 rai of land in Bang Len as well as Nakhon Chai Si District.
