Deluz () is a commune in the Doubs department in the Bourgogne-Franche-Comté region in eastern France.
The construction of the RhôneâÂÂRhine Canal in 1821 created a narrow spit of land which, along with the water power from the weir, allowed the development of cloth spinning (1858âÂÂ1872) and paper making (1873âÂÂ1977). The abandoned buildings now house a small hydroelectric plant.
