Theta Cobrini V was a planet located somewhere in the space of the galaxy's Alpha or Beta Quadrants, the fifth planet in orbit of the Theta Cobrini star system.

In 2267, the Federation built an outpost on Theta Cobrini V capable of scanning deep into the Romulan Star Empire. Later the same year, the Klingon Empire destroyed the outpost and then the Romulan forces sent to carry out the same task. (ST - Seven Deadly Sins novella: The First Peer)
