Sylvie Corteel and Jeremy Lovejoy [7] defined overpartitions and George E Andrews derived formula for the number of smallest parts of partitions of a positive integer n. In this paper the concepts of jth overpartition and r-jth overpartition of n are introduced and a formula for the number of smallest parts of the jth overpartition is derived by using r-jth overpartitions of n.
