The Laplacian spread s(G) of a graph G is defined to be the difference between the largest eigenvalue and the second-smallest eigenvalue of the Laplacian matrix of G. Several upper bounds of Laplacian spread and corresponding extremal graphs are obtained in this paper. Particularly, if G is a conne
