  We study the shadow of a rotating squashed Kaluza-Klein (KK) black hole and
the shadow is found to possess distinct properties from those of usual rotating
black holes. It is shown that the shadow for a rotating squashed KK black hole
is heavily influenced by the specific angular momentum of photon from the fifth
dimension. Especially, as the parameters lie in a certain special range, there
is no any shadow for a black hole, which does not emerge for the usual black
holes. In the case where the black hole shadow exists, the shadow shape is a
perfect black disk and its radius decreases with the rotation parameter of the
black hole. Moreover, the change of the shadow radius with extra dimension
parameter also depends on the rotation parameter of black hole. Finally, with
the latest observation data, we estimate the angular radius of the shadow for
the supermassive black hole Sgr $A^{*}$ at the centre of the Milky Way galaxy
and the supermassive black hole in $M87$.
