Jeannie Kelly was a Human female living in the early-21st century, the wife of John Kelly.

Her husband promised to bring her back a "Mars rock" from his mission on the Ares IV, but unfortunately the ship was engulfed by a graviton ellipse. He was presumed dead upon contact.

Unknown to Jeannie or the ISA, he had survived for several more days. In 2376, the USS Voyager and Seven of Nine found the Ares IV module inside the ellipse, and watched his mission records, wherein he apologized to Jeannie for not being able to bring her that Mars rock, and that he kept a photograph of her next to his console until the end. (VOY: "One Small Step")

Jeannie Kelly was portrayed by an unknown actress.
Jeannie Kelly was described as the daughter of John Kelly in the Star Trek Encyclopedia (4th ed., vol. 1, p. 410).
