Naiad (planet)

Naiad was an oceanic planet, presumably in the Alpha or Beta Quadrants. 

It was also the name of a race presumably native to this world. A Naiad was in a bar on Ryn III in 2336, gossiping about Starfleet covert operatives on the planet investigating the Orion Syndicate. This conversation was overheard by the Starfleet operatives, alerting them that their covers had been compromised.
