A weight estimation device for a vehicle includes a storage unit storing a weight calculation information indicating a correspondence between an internal pressure value of an air spring supporting a vehicle body and a vehicle height serving as a height of the vehicle body from a base, a measured value acquisition unit acquiring a measured internal pressure value and a measured vehicle height, an internal pressure value calculation unit calculating a corrected internal pressure value of the air spring by deducting or adding a corrected value from or to the measured internal pressure value in a case where the measured internal pressure value is greater or smaller than the internal pressure value of the weight calculation information which corresponds to the measured vehicle height, and a weight calculation unit calculating a weight of a supported body, including the vehicle body, based on the corrected internal pressure value.
