Many researchers study rough sets from the point of view of description of the rough set pairs(a rough set pair is also called a rough set), i.e. "lower approximation set, upper approximation set". Dai [4] showed that all the rough sets in an approximation space constructs a 3-valued Łukasiewicz algebra. The constructed algebra is called the rough 3-valued Łukasiewicz algebra. It is shown that a rough 3-valued Łukasiewicz algebra is an MV-algbra in this paper. The direct relation between rough set theory and MV-algebras is constructed. The definition of rough MV-algebras is also given.
