Let G = ( V ( G ), E ( G )) be a connected graph and is coloring of graph G . Let Π = { C 1 , C 2 , …, C k }, where C i is the partition of the vertex in which is colored i with 1 ≥ i ≥ k . The representation v for Π is called the color code, denoted C Π ( v ) is a ordered pair with k -element namely, C Π ( v ) = ( d ( v , C 1 ), d ( v , C 2 ), …, d ( v , C k )), where d ( v , C i )= mind{ d ( v

The minimum number of colors used in G is called chromatic locating, notated by X L ( G ). In this paper, we will determine the locating coloring of graph cubic C n,2n,n , for n=3,4,5.
