Berek (Oromo: Barihee) is a woreda or district in Oromia Region, Ethiopia. It was part of the former Berek Aleltu woreda which was separated for Aleltu and Berek woredas and Sendafa Town.

The landscape of this woreda has been described as undulating mountains covered by a scattered settlement pattern, which make development efforts more difficult.^[1]

This Program operates in 12 of the woreda's kebeles, with the goal of improving agricultural practices, developing new rural water sources, conserving use of local natural resources, training community health workers and building new schools.^[1]
