An axionic Kerr black hole solution, which has Kerr-like metric and non-vanishing axionic field strength, has been found exactly by solving the stationary axisymmetric Einstein axion field equation. It indicates that there exists an axionic hair for the rotating black hole and the axionic hair can be detected by strings directly, without resorting to the Aharonov-Bohm process. In addition, some interesting characteristics for the structure of an axionic Kerr black hole are also studied.
