Mahakali was one of the fourteen zones located in the Far-Western Development Region of Nepal, covering an area of 6,205 km2 in the westernmost part of the country. It stretches along Nepal's far western border with India, marked by the Kali River or Mahakali River. In 2015 Nepal discontinued use of zone designations in favor of provinces. The zone formerly known as Mahakali is now part of Sudurpashchim Province. Mahakali's headquarters is Bhimdatta in Kanchanpur District.
