%X We investigate the electromagnetic perturbation around a stringy black hole. A second-order differential equation is obtained for the perturbation. The variation of the effective potential with r is presented. The complex frequencies of the quasinormal modes of electromagnetic perturbation around a stringy black hole are computed by the third Wentzel--Kramers--Brillouin (WKB) approximation. The results show that the parameters resulted from thecompactification of higher dimensions can influence the quasinormal complexfrequencies, and the Maxwell field around a stringy black hole damps moreslowly than that around a Schwarzschild black hole.
