  We have investigated the shadow of a Konoplya-Zhidenko rotating non-Kerr
black hole with an extra deformation parameter. The spacetime structure arising
from the deformed parameter affects sharply the black hole shadow. With the
increase of the deformation parameter, the size of the shadow of black hole
increase and its shape becomes more rounded for arbitrary rotation parameter.
The D-shape shadow of black hole emerges only in the case
$a<\frac{2\sqrt{3}}{3}M$ with the proper deformation parameter. Especially, the
black hole shadow possesses a cusp shape with small eye lashes in the cases
with $a>M$, and the shadow becomes less cuspidal with the increase of the
deformation parameter. Our result show that the presence of the deformation
parameter yields a series of significant patterns for the shadow casted by a
Konoplya-Zhidenko rotating non-Kerr black hole.
