Jisa was a Vaadwaur soldier and the wife of Gedrin who lived during the 15th century.

In the Earth year 1484, she and a group of about 600 Vaadwaur went into stasis on their homeworld after an attack by their enemies, including the Turei. She was among those who died when the stasis equipment malfunctioned. The rest of the Vaadwaur were not released from stasis until 2376, 892 years later. (VOY: "Dragon's Teeth")
