The notion of rough sets was introduced by Z. Pawlak in the year 1982. The notion of a $\Gamma$ -semigroup was introduced by M. K. Sen in the year 1981. In 2003, Y. B. Jun studied the roughness of sub $\Gamma$ -semigroups, ideals and bi-ideals in i-semigroups. In this paper, we study rough prime ideals and rough fuzzy prime ideals in $\Gamma$ -semigroups.
