Sam Chuk District  Sam Chuk District (, ) is a district ("amphoe") in the northern part of Suphan Buri Province, central Thailand. Originally the district name was "Nang Buat".

In 1939 the district name was changed to Sam Chuk as the central tambon.

The main water resource of Sam Chuk is the Tha Chin River or Suphan river.
