Chom Phon Ruea (Thai: จอมพลเรือ, lit. 'Boat marshal') or Admiral of the Fleet is the most senior naval officer rank of the Royal Thai Navy. Today it is only ceremonially held by members of the Thai Royal family. The Royal Thai Army equivalent is known as just Chom Phon and Chom Phon Akat for the Royal Thai Air Force.
The rank was formally created in 1888, together with all other ranks of the military by King Chulalongkorn (Rama V), who wanted to modernize his Armed Forces through western lines.
