Vinna Jiss was a female Human Grand Army of the Republic logistics employee who worked under Besany Wennen and sided with the Separatists during the Clone Wars.
In 21 BBY, Vinna met with Paxaz Izhiq, a Falleen criminal, and made a deal to exchange illegal goods in a warehouse-block between two freighters. However, she was captured by clone commandos Fi and Sev, who interrogated her for information. After explaining everything to them, she was ultimately executed by Walon Vau. Jinart the Gurlanin later impersonated her form, not knowing that the real Vinna Jiss had been killed by Vau.
Vinna Jiss was described by her supervisor as an undependable worker.
