The Ibaloi (also spelled Ibaloy; Ibaloi: ivadoy, /ivaˈdoj/) are an indigenous ethnic group found in Benguet province of the northern Philippines. Ibaloi is derived from i-, a prefix signifying "pertaining to" and badoy or house, together then meaning "people who live in houses". The Ibaloi are one of the indigenous peoples collectively known as Igorot (igudut, "hill-dwellers"), who live in the cordillera central of Luzon.
The Ibaloi inhabit the southeastern part of Benguet Province. The area is rich in mineral resources like copper, gold, pyrite, and limestone. Plants and animals are also abundant in the forests and mountain areas, and there is an extensive water system that includes the Bued River, Agno River, and Amburayan River. Mount Pulag, the third highest mountain of the Philippines, is found in their territory and is a culturally important area as well, considered the place where spirits join their ancestors.
The Ibaloi are distributed in the mountain valleys and settlements. Their ancestors are likely to have originated from the Lingayen and Ilocos coasts, who then migrated into the Southern Cordillera range before settling. Ancestral land claims by Ibaloi communities include parts of Baguio.
The native language of the Ibaloi people is Ibaloi, also known as Inibaloi or Nabaloi. It has three dialects: Bokod, Daklan and Kabayan. The Ibaloi often also speak Ilocano and Tagalog as a second language.
Ibaloi society is composed of the rich (baknang) and three poor classes, the cowhands (pastol), farmhands (silbi), and non-Ibaloi slaves (bagaen).
The Ibaloi have a rich material culture, most notably their mummification process, which makes use of saltwater to prevent organ decomposition. Pounded guava and patani leaves are applied to the corpse to prevent maggot or worm infestation while the body dries, the process taking anywhere from two months to even a year until the body is hardened.
The Ibaloi build their houses (balai or baeng) near their farms. These are usually built on five foot posts (tokod) and contain only one room with no windows.
