The aim of this work is to characterize almost $*-$Ricci-Yamabe solitons on a Sasakian manifold where we proved that the manifold is isometric to the unit sphere $\mathbb{S}^{2n+1}$ if its metric represents a complete almost $*-$Ricci-Yamabe solitons with $\alpha\neq0$. Certain conditions under which the soliton reduces to $*$-Ricci-Yamabe soliton and when it becomes steady is also obtained.
