Mulukuku is a municipality in the North Caribbean Coast Autonomous Region of Nicaragua. It was established as an asentimiento, or refugee community, during the early years of the war with the contra. People who lived in the remote rural areas and who were threatened by the contra, were brought to Mulukuku for safety. During the war a training school for the Nicaraguan army was located in the community. The community straddled the only road in the region that connected the Department of Matagalpa with Lisawe, Siuna, and eventually Puerto Cabezas. A large bridge crossing the Rio Tuma had been under construction and was nearly complete, when, in October 1988, Hurricane Joan struck Nicaragua. The bridge was destroyed and the community devastated. The national government committed to reconstruction and the community has flourished since that time. With the bridge complete, Mulukuku has become a regional commercial center. "Mulukukú" is a word in Miskito language that means Rivera de Sahinos.
