Duhan Vos was a joined male Trill in the 24th century. The Vos symbiont was joined to Duhan circa the year 2352.

Vos resided on the colony world Shal Tul, and worked as a chemical engineer. Circa 2372, the Vos symbiont—and Duhan Vos' identity—was stolen by Verad, with the help of Bethan Roa. Duhan was then admitted to Gheryzan Hospital under Verad's name.

Posing as Duhan Vos, Verad ran for and was elected to the Trill Symbiosis Commission in 2372. (DS9 short story: "Reflections")
