To provide a marine LED lighting device that can sufficiently dissipate heat generated from an LED board and a power supply board without using metal components that come into contact with outside air.SOLUTION: Light emitted from an LED component 27 arranged in an interior space S enclosed by a body 2 and a glove 3 is transmitted through the glove 3 and diffused to an outside. The marine LED lighting device comprises: a power supply board 4 which is arranged on a mounting base 7 of the body 2 across a first space S1 and has a semiconductor component 22 mounted thereon; and an LED board 5 which is arranged on the power supply board 4 across a second space S2 and has the LED component 27 mounted thereon. A heat-dissipating connection member 6 arranged in the first space S1 and having one end attached to the mounting base 7 of the body 2 and the other end in contact with the semiconductor component 22 mounted on the power supply board 4 is provided. A heat-dissipating board 12 facing the first space S1 is provided in the mounting base 7 of the body 2. A heat-dissipating plate 29 facing the second space S2 is provided in the LED board 5.SELECTED DRAWING: Figure 2
