Thana or Thâṇâ (Bengali: থানা means "police station" in Bangladesh and can also mean the district controlled by a police station.
Thana was a subdistrict in the administrative geography of Bangladesh. The Local Government Ordinance of 1982 was amended a year later, redesignating and upgrading the existing thanas as upazilas. Later in 1999 geographic regions under administrations of thanas were converted into upazilas. All administrative terms in this level were renamed from thana to upazila. The word thana is now used to solely refer to police stations. Generally, there is one police station for each upazila; but larger administrative units may have more than one police station covering different regions.
