Disclosed is a urea storage tank cooling system using a fuel oil cooler. According to the present invention, the urea storage tank cooling system includes: a fuel oil circulation line supplying fuel oil to an engine of a vehicle; a heat exchanger installed on the fuel oil circulation line to cool fuel oil supplied to the engine; a cooler supplying cooled coolant to the heat exchanger; a coolant supply line supplying the coolant from the cooler to the heat exchanger; a urea storage tank storing urea supplied as a reducing agent of an SCR device provided in the vessel; a first cooling line branched from the coolant supply line at the front end of the heat exchanger, and cooling the urea storage tank by using the coolant supplied from the cooler as cooling fluids; and a second cooling line branched from the coolant supply line at the rear end of the heat exchanger, and cooling the urea storage tank by using the fuel oil cooled by the heat exchanger as cooling fluids. Either of the first and second cooling lines is selectively used to cool the urea storage tank.
