Provided is an organic solvent recovery system comprising a treatment tank in which there is accommodated an adsorbent material by which an organic solvent is adsorbed and removed from an organic-solvent-containing gas being treated. The organic solvent recovery system also comprises: an organic solvent recovery device that repeatedly carries out an adsorption treatment in which the gas being treated that is supplied to the treatment tank is brought into contact with the adsorbent material and a treatment gas is discharged, and a desorption treatment in which the organic solvent is desorbed from the adsorbent material by using water vapor for desorption that is supplied to the treatment tank and a desorption gas is discharged; a heat exchanger having a heating unit through which flows the desorption gas discharged from the organic solvent recovery device, and a heat-absorbing unit to which replenishment water is supplied, the heat exchanger indirectly heating the replenishment water in the heat-absorbing unit by using the desorption gas flowing through the heating unit to generate water vapor, and discharging the indirectly heated desorption gas; and a cooling unit that cools the desorption gas discharged from the heat exchanger and discharges a condensed liquid. The organic solvent recovery system additionally comprises a water vapor supply unit that supplies the water vapor to the heating unit of the heat exchanger. The heat exchanger supplies the water vapor generated from the replenishment water to the organic solvent recovery device as at least part of the water vapor for desorption.
