This paper explores the shadow cast by a non-commutative rotating Hayward black hole. The apparent shape as well as the size of the shadow depends upon the spin, non-commutative parameter as well as the parameter g of the said black hole. The size of the shadow decreases with g as well as the non-commutative parameter. Also, the shape of the shadow deviates from a perfect circle for the high values of g and the spin. We then discuss the rate of energy emission. Moreover, we study the impact of plasma on the size, shape as well as the rate of energy emission. We found that the plasma reduces the size and deformation of the shadow.
