Boloso Sore is one of the woredas in the Southern Nations, Nationalities, and Peoples' Region of Ethiopia. Part of the Wolayita Zone, Boloso Sore is bordered on the south by Sodo Zuria and Damot Sore, on the west by Boloso Bombe, on the northeast by the Kembata Tembaro Zone, on the northeast by the Hadiya Zone, on the east by Damot Pulasa, and on the southeast by Damot Gale. The administrative center is at Areka. Boloso Bombe and Damot Sore woredas were separated from Boloso Sore.
Landmarks in this woreda include three megalithic sites with one stele in each; one of these sites is Cheme Hembico. Near the She'a river there is a site with animal engravings; obsidian and ceramic fragments have been observed on the surface of the She'a site.
Boloso Sore has 57 kilometers of all-weather roads and 74 kilometers of dry-weather roads, for an average road density of 206 kilometers per 1000 square kilometers. The woreda is culturally homogeneous with Welayta-speaking people, though a small but active minority of Protestant and Catholic converts formed a sub-culture.
A survey of land reform in the area which became Boloso Sore was performed in 1980-1981 under the direction of Dessalegn Rahmato. It found that Bolosso is "the beneficiary of many years of infrastructural and extension service by the Wollaita Agricultural Development Unit". Further, although the area had been self-sufficient in food in years past, there were clear signs of gradual impoverishment. In a 1971 survey about 30% of Bolosso households did not use ox-drawn ploughs for cultivation; ten years later, 52% of the peasants interviewed did not own oxen.
Prime Minister Tamirat Layne on 1 June 1994 began touring villages affected by famine in Boloso Sore. In this woreda alone, over 5,000 people had so far died of famine or malaria, 60% of them being children.
