A road surface friction coefficient calculation apparatus to be applied to a vehicle includes an obtainer and a determiner. The obtainer is configured to acquire n pieces of sensor data periodically obtained by a predetermined sensor during a predetermined period. The determiner is configured to determine a road surface condition in front of the vehicle by making a majority decision on road surface conditions, based on the n pieces of sensor data acquired by the obtainer. The determiner is configured to set a different road surface friction coefficient for each of the road surface conditions, and determine a road surface friction coefficient in front of the vehicle, based on the road surface friction coefficient corresponding to the road surface condition determined by the majority decision.
