Mamasa Regency (Indonesian: Kabupaten Mamasa), covering a land area of 3,005.88 km2 with its capital at Mamasa city, is the only inland regency without a coast among the six regencies that make up the West Sulawesi (Sulawesi Barat) Province on the island of Sulawesi in Indonesia. The Mamasa people, a sub-group of the Toraja people, form the most common ethnic group. Despite being the home to the Gandang Dewata National Park, the regency has immense untapped tourism potential hindered by the political apathy towards developing the transport and tourism infrastructure, which is keeping the local populace in poverty.
