Masha Anderacha was one of the 77 woredas in the Southern Nations, Nationalities, and Peoples' Region of Ethiopia. Part of the Keficho Shekicho Zone, Masha Anderacha was bordered on the south by Yeki, on the west and north by the Oromia Region, and on the east by Gesha. Towns in Masha Anderacha included Gecha and Masha. Masha Anderacha was separated for Anderacha and Masha woredas.

This woreda is notable for its relatively high forest cover as compared to other parts of Ethiopia, accounting in 2001 for about 56% of the country's total forested area; this woodland is primarily governed by a form of tenure known as Kobo, which promotes the existence of woodland for hunting and beekeeping. However this resource is threatened by the growth of tea and coffee plantations. Important cash crops include corn, teff, wheat, pulses and enset.

In September 2003, cadres of the Ethiopian People's Revolutionary Democratic Front (EPRDF) threatened to take away the land in the woreda occupied by eight farmers, who were supporters of the United Ethiopia Democratic Party (UEDP). The EPRDF cadres told the farmers that opposition party members were not entitled to land and demanded that they cease their support for the UEDP. When the farmers refused to comply with this demand, they were evicted from their land. The following month, two teachers were fired for being members of UEDP.

Masha Anderacha was selected by the Ministry of Agriculture and Rural Development in 2004 as one of several woredas for voluntary resettlement for farmers from overpopulated areas, becoming the new home for a total of 512 heads of households and 2048 total family members.

Based on figures published by the Central Statistical Agency in 2005, this woreda has an estimated total population of 67,972, of whom 35,276 are men and 32,696 are women; 13,210 or 19.43% of its population are urban dwellers, which is greater than the Zone average of 9.7%.
