A system for predicting a road surface friction coefficient includes an external information acquisition part, a tire information acquisition part, and a friction coefficient prediction part. The external information acquisition part configured to acquire external information on a disturbance factor that affects a condition of a road surface on which a target vehicle travels. The tire information acquisition part configured to acquire tire information indicating a condition of a tire of the target vehicle. The friction coefficient prediction part configured to predict a friction coefficient between the tire and the road surface based on the tire information acquired by the tire information acquisition part and the external information acquired by the external information acquisition part. The friction coefficient prediction part predicts a friction coefficient of a road surface ahead of the target vehicle in a traveling direction.
