Seti (Nepali: सेती अञ्चलListen) was one of the fourteen zones located in the Far-Western Development Region of Nepal. Dhangadhi in the Terai is the major city of Seti Zone; headquarters are in Dipayal-Silgadhi. As of 2015, Nepal discontinued zone designations in favor of provinces; the area previously known as Seti Zone is now part of Sudurpashchim Province.

Seti was divided into five districts; since 2015 these districts have been redesignated as part of Sudurpashchim Province.
