The Vensiddians were a species native to the Delta Quadrant. They were among those who participated in the sport of Tsunkatse.

During USS Voyager's shore leave at Norcadia Prime in 2376, Chakotay favored the Vensiddian as the winner of the seventh Tsunkatse match. Though the Vensiddian had lost his previous two matches, Chakotay noted he was undefeated against left-handed fighters. (VOY: "Tsunkatse")
