A shield for a vehicle side view mirror comprises a main deflector body forming a hood with a lip extending from the deflector body configured to abut a surface of the minor. In a preferred embodiment a secondary deflector body extends rearwardly from the main deflector body opposite the lip. When the lip is attached to the mirror the shield is interposed in a space between the windshield and a reflective surface of the mirror, to deflect water and debris being cleared from the windshield thereby shielding the reflective surfaces of the mirror.
