To provide a coolant control device of a marine internal combustion engine which can properly control a jacket coolant in a cooling system of a marine internal combustion engine.SOLUTION: A coolant control device 1 of a marine internal combustion engine controls a jacket coolant of a cooling system 50 including a cooler 53 and a waste-heat utilization device 54 at a coolant circulation path 52 of a marine internal combustion engine 51. The coolant control device 1 includes: temperature detection means 2a, 2b which detect a temperature of the jacket coolant passing through the marine internal combustion engine 51; first bypass means 3 which adjusts a bypass flow rate of the jacket coolant which bypasses the coolant 53; second bypass means 4 which adjusts a bypass flow rate of the jacket coolant which bypasses the waste-heat utilization device 54; and control means 10 which controls operations of the first bypass means 3 and the second bypass means 4 based on detection of the temperature detection means 2a, 2b.SELECTED DRAWING: Figure 1
