A tehsil (Hindustani: [t̪ɛɦsiːl], also known as tahsil, taluk, or taluka (IPA: [t̪aːluːkaː t̪aːluːku]) is a local unit of administrative division in India and Pakistan. It is a subdistrict of the area within a district including the designated populated place that serves as its administrative centre, with possible additional towns, and usually a number of villages. The terms in India have replaced earlier terms, such as pargana (pergunnah) and thana.
In Andhra Pradesh and Telangana, a newer unit called mandalamu (circle) has come to replace the tehsil system. A mandal is generally smaller than a tehsil, and is meant for facilitating local self-government in the panchayat system. In West Bengal, Bihar, Jharkhand, community development blocks (CDBs) are the empowered grassroots administrative unit, replacing tehsils.
