Disclosed are a system and a method for measuring a marine wave height which measure a wave height for a wide range of water surfaces in real time. The system for measuring a marine wave height comprises an unmanned aerial vehicle and a controller to control the flight of the unmanned aerial vehicle and use measurement data received from the unmanned aerial vehicle to calculate a wave height. The unmanned aerial vehicle includes: a location measurement unit to use a global navigation satellite system (GNSS) to measure the absolute location of the unmanned aerial vehicle; an attitude measurement unit to measure the attitude of the unmanned aerial vehicle; and a time-of-flight (TOF) camera to measure the location of a water surface. The controller controls to measure the absolute location and attitude of the unmanned aerial vehicle and the location of the water surface, calculates the absolute location of the water surface from a water surface measurement location through relative coordinate system conversion, and subtracts a water surface measurement location without disturbance from the absolute location of the water surface to calculate a wave height displacement amount.
