In this paper, we consider *-Ricci soliton in the frame-work of Kenmotsu manifolds. First, we prove that if ( M ,  g ) is a Kenmotsu manifold and  g  is a *-Ricci soliton, then soliton constant λ is zero. For 3-dimensional case, if  M  admits a *-Ricci soliton, then we show that  M  is of constant sectional curvature –1. Next, we show that if  M  admits a *-Ricci soliton whose potential vector field is collinear with the characteristic vector field  ξ , then  M  is Einstein and soliton vector field is equal to  ξ . Finally, we prove that if  g  is a gradient almost *-Ricci soliton, then either  M  is Einstein or the potential vector field is collinear with the characteristic vector field on an open set of  M . We verify our result by constructing examples for both *-Ricci soliton and gradient almost *-Ricci soliton.
