Centurion Nilona was a Romulan military officer during the 2260s.

In 2267, he served as the helmsman aboard the IKS Kretoq when it faced the USS Defiant while testing the Kretoq's new cloaking device. Later that year, Nilona was still serving aboard the Kretoq during its aborted attempt to attack Theta Cobrini V and subsequent engagement with Klingon forces. (ST novella: The First Peer)
