Hosc T'Mar was a male Trill Starfleet officer, born in the 24th century.

Due to the loss of many Starfleet officers during the Borg Invasion of 2381, T'Mar became captain prematurely. Fellow Captain Regina Farkas and her chief medical officer, Dr. El'nor Sal, considered him young and inexperienced, with Sal stating he would have been someone's executive officer for the next five years if not for the Borg invasion.

In 2381, T'mar was the commanding officer of the USS Planck during that vessel's exploration of the Delta Quadrant. (VOY novel: Children of the Storm)

Planck's first mission was to investigate a non-corporeal species, called "Children of the Storm", together with USS Demeter. Four days into the mission T'Mar intended to boost his crew's morale, which was affected by the malfunctioning replicators, by requesting organic foodstuff from USS Demeter. The transfer aroused the interest of the Children of the Storm. Captain Farkas' attempt to parlay with them failed and the Children surrounded Planck and destroyed the ship, killing everyone aboard.
