Abstract: The Sombor energy of a graph is the sum of the absolute values of the eigenvalues of the Sombor matrix of the graph.By applying matrix theory and inequality properties,as well as the relationship between the Sombor energy of a graph and the energy of the graph,several new upper bounds of the Sombor energy of circulant graphs are obtained.

Key words: circulant graph, Sombor energy, upper bound
