Bang Len of Nakhon Pathom Province.

History

At first the area was administrated from Amphoe Bang Bua Thong. On January 1 1948 four tambon were split off to from the new minor district (''king amphoe'') Sai Noi. On June 6 1956 it was elevated to full district status.
In 1971 the Tambon Khun Si was transferred from Amphoe Bang Len (Nakhon Pathom) to become part of Si Noi.
In 1979 the southern part of Tambon Rat Niyom formed the new Tambon Khlong Khwang. The following year the southern part of Tambon Sai Noi was split off to create Tambon Thawi Watthana.

Administration

The district is subdivided into 7 subdistricts (''tambon''), which are further subdivided into 67 villages (''muban''). Sai Noi itself has township status (''thesaban tambon'') which covers parts of ''tambon'' Sai Noi and Khlong Khwang. There are further 7 tambon administrative organizations (TAO).
