Jeanne Bal (May 3, 1928 – April 30, 1996) was an American actress and model who worked primarily in 1960s television.

Her other television credits include four appearances on Perry Mason, including the role of Dr. Linda Carey in the 1962 episode, "The Case of the Angry Astronaut", and murder victim Vera Wynne in the 1965 episode, "The Case of the Telltale Tap".

In 1963, she guest-starred as Melissa, an overly ambitious saloon girl, on Bonanza in the episode "The Saga of Whizzer McGee."

In "The Man Trap" (1966), the very first episode of the original Star Trek series, she played a lethal shape-shifting alien which craves salt.

Initially, plans called for increasing her role for the 1964–65 season, promoting her to second billing on the show, but the producer instead cut the number of episodes in which she was to appear.
