In this paper, we define a new concept in theory of graph energy called coneighbor energy of a graph G, denoted by
CE(G), as the sum of the absolute value of eigenvalues of its coneighbor matrix. We are going to derive some results about the
coneighbor energy of graphs and coneighboracation graph that possess some coneighbor vertices.
