| Abstract: | The matching energy of a graph was defined as the sum of the absolute values of zeros of its matching polynomial.Let U(n,d) be the set of connected unicyclic graphs of order n and diameter d,the graph from U(n,d) minimizing the matching energy is completely characterized. |

| Keywords: | matching energy unicyclic graph diameter |
