R'ongovia was an inhabited star system in the Beta Quadrant. Home for the R'ongovians, it was the capital system of their R'ongovian Protectorate.
In 2259, the location of this system was labeled in a stellar cartography chart seen on the USS Enterprise's ready room viewscreen. The system's symbol had a yellow color.
When Tellarite Ambassador Q'Ral was confronted by R'ongovian Captain Vasso L'Gaelia, he was told that "every word you speak is an insult to R'ongovia." (SNW: "Spock Amok")
