Abstract：

Let　G　be　a　graph　of　order　n.　Let　λ1,　λ2,　...　,　λn　be　the　eigenvalues　of　the　adjacency　matrix　of　G,　and　let　μ1,　μ2,　...　,　μn　be　the　eigenvalues　of　the　Laplacian　matrix　of　G.　Much　studied　Estrada　index　of　the　graph　G　is　defined　as　We　define　and　investigate　the　Laplacian　Estrada　index　of　the　graph　G,　Bounds　for　LEE　are　obtained,　as　well　as　some　relations　between　LEE　and　graph　Laplacian　energy.
