If the n th centered polygonal number is denoted by ) (n, where k≥3 is the number of sides of the polygon.For 3 k , itgives centered triangular numbers.For 4 kgives centered tetragonal numbers and so on.In this paper, we introduce the centered polygonal graceful labeling and we prove that the star, subdivision of the star, path, coconut tree, bistar and comb graph are centered polygonal graceful graphs.
