The present invention provides a urea solution supply system capable of minimizing costs consumed for bunkering a urea solution and maintaining temperature of the urea solution. According to an embodiment of the present invention, the urea solution supply system includes: a urea solution tank storing the urea solution; a selective catalytic reduction reactor receiving the urea solution from the urea solution tank and reducing nitrogen oxide included in exhaust gas generated in a combustion engine of a vessel; a urea solution supply pipe connecting the urea solution tank and the selective catalytic reduction reactor; a sensor unit installed on the urea solution supply pipe, and measuring the concentration of the urea solution; a concentration control unit controlling the concentration of the urea solution to a standard concentration by injecting the urea solution for controlling the concentration into the urea solution supply pipe at a rear end of the sensor unit; and a control unit controlling a movement of the concentration control unit by being interlocked with the sensor unit.
