Relay Station 194 was a Federation communication relay station that was in service with Starfleet in the mid-24th century. It was located near Relay Station 47.

In 2369, this station was offline for maintenance and asked Station 47 to handle their com traffic during the shutdown. While Lt. Keith Rocha refused, claiming they couldn't handle the additional signal load, his junior officer, Aquiel Uhnari, believed he was wrong and secretly accepted Relay Station's 194 request. (TNG: "Aquiel")

This station was only mentioned in dialogue.
According to Star Trek: Star Charts (p. 65) and Stellar Cartography: The Starfleet Reference Library ("Federation Historical Highlights, 2161-2385"), Relay Station 194 was located in the Beta Quadrant.
