Abstract: In this paper, the shadow casted by the rotating black hole inspired by noncommutative geometry is investigated. In addition to the dimensionless spin parameter a / M 0 with M 0 black hole mass and inclination angle i , the dimensionless noncommutative parameter √ϑ/ M 0 is also found to affect the shape of the black hole shadow. The result shows that the size of the shadow slightly decreases with the parameter √ϑ/ M 0 , while the distortion increases with it. Compared to the Kerr black hole, the parameter √ϑ/ M 0 increases the deformation of the shadow. This may offer a way to distinguish noncommutative geometry inspired black hole from Kerr one via astronomical instruments in the near future.
