A set of vertices a graph if every pair of adjacent vertices is uniquely determined by its coordinate of distances to the vertices in . The minimum cardinality of a local resolving set of is called the of . A graph is called a -regular graph if every vertex of is adjacent to other vertices of . In this paper, we determine the local metric dimension of an -regular graph of order , where .
