In this work we introduce the notion of fuzzy Volterra difference equations and study the dynamical properties of some classes of this type of equations. We prove some comparison theorems for these equations in terms of ordinary Volterra difference equations. Using these results the stability of the fuzzy nonlinear Volterra difference equations is investigated.
