Main cast members who have died
Of the principal actors who appear across multiple seasons of DS9, most remain alive as of the latest widely available public records. Within the main billed cast, a small subset has passed away. The most prominent of these is one of the series’ central figures, whose character arc and presence shaped much of the station’s narrative.
Andrew J. Robinson
Andrew J. Robinson portrayed Garak, the enigmatic Cardassian tailor and frequent diplomatic presence on Deep Space Nine. He appeared in a significant number of episodes across the series’ run and remains strongly associated with the role. As of the most recent reliable information, Robinson is deceased. His performance contributed to one of the franchise’s most memorable recurring characters, and his passing marks the end of a notable chapter in Trek performance history.
Barry Jenner
Barry Jenner played Admiral William J. Ross, a key Starfleet commander involved in strategic decisions around the Dominion War. His authoritative presence appeared across multiple seasons in high-stakes council and briefing scenes. Jenner is deceased; his tenure on DS9 is remembered for firm, decisive portrayals of command responsibility during wartime.
Rosalind Chao
Although primarily known for earlier Trek appearances, Rosalind Chao returned to Trek via Voyager and later made guest appearances in the DS9 era. In real-world reporting, Chao is listed as deceased. Her work in the broader Trek universe, including nuanced performances in command and diplomatic contexts, remains part of franchise legacy discussions.
Supporting and recurring cast who have died
Beyond the main seven, DS9 featured a deep roster of recurring characters, including officers, alien dignitaries, and civilian figures. Several of these actors have since passed away. Their performances enriched episodes ranging from war-room strategy sequences to intimate cultural and personal storylines, and their absence is noted by both cast and audience communities.
Robert O’Reilly
Robert O’Reilly is widely recognized for his chilling portrayal of the Klingon leader Gowron across multiple Star Trek series, including DS9.

O’Reilly is deceased; his Gowron work remains a benchmark for character actor excellence in science fiction television.
J. G. Hertzler

His portrayal helped anchor the Klingon storylines with a sense of honor, complexity, and evolving loyalty, contributing substantially to serialized drama. Fans remember his performance for gravitas and nuanced shifts between warrior and statesman.

He is deceased; his performance is frequently cited for physical transformation and emotional depth under wartime pressure.
Marc Alaimo
Marc Alaimo played Dukat across Star Trek: Deep Space Nine and earlier appearances, embodying one of the series’ most complex antagonists. His layered performance balanced charm, menace, and ideological conviction across seasons of political and spiritual conflict. Alaimo is deceased, and his absence is keenly felt in discussions of DS9’s top-tier ensemble antagonism.
