A road surface state detection apparatus includes a light emitter, an optical sensor, and an electronic control unit. The light emitter is configured to project an image with visible light on a road surface below a side of a vehicle. The optical sensor is provided on the side of the vehicle and configured to receive reflected light from the projected image. The electronic control unit is configured to determine a state of the road surface based on the reflected light received by the optical sensor.
