To provide a vehicle collision analysis system capable of more objectively analyzing and informing of deformation of the vehicle and damage status by collision.

The vehicle collision analysis system comprises a plurality of acceleration sensors 20L, 20R or the like mounted to a predetermined part of the vehicle and detecting acceleration applied to a vehicle body; a collision determination part 32 for receiving acceleration signals from the plurality of acceleration sensors and determining danger of the collision; occupant protection devices 37L, 37R or the like receiving an instruction signal from the collision determination part, operated and protecting the occupant; a deformation presumption part 35 for presuming the deformation state of the vehicle body; and a communication device 40 for informing the outside of presumption result at the deformation presumption part.
