    We develop a theory of optomechanical cooling with a squeezed input light field. We show that Stokes heating transitions can be emph{fully} suppressed when the driving field is squeezed below the vacuum noise level at an appropriately selected squeezing phase and for a finite amount of squeezing. The quantum backaction limit to laser cooling is therefore moved down to zero and the resulting final temperature is eventually solely determined by the ratio between the thermal phonon number and the optomechanical cooperativity parameter independently of the actual values of the cavity linewidth and mechanical frequency. The cooling rate remains instead unchanged with respect to standard optomechanical cooling schemes.
