Chandūka, also spelled Chāndkoh or Chāndko, was a historical region in Sindh, roughly corresponding to the Larkana subdivision as it existed in the early 20th century. It was an alluvial tract on the right bank of the Indus with its main town at Ghaibi Dero. S.H. Hodivala also wrote in 1939 that Chanduka was then the name of the main town in Larkana District. Chanduka is named after the Baluch tribe known as the Chandias.
