Chief Engineer Michael Hronsky was a Starfleet officer during the 2260s.

In 2267, he was the chief engineer at the Cestus III outpost. He met Captain Picard (at the time using the alias Dixon Hill) after he was thrown through time and space to Cestus III. Hronsky was about to activate the outpost's new sensor array when he was stunned by Picard, because the core powering the array would destroy the outpost. He would be knocked unconcious again as Picard attempted to flee. (TNG novel: Requiem)
