Janet Waldo was an American voice actress, perhaps best known as the voices of Judy Jetson on Hanna-Barbera's The Jetsons (also starring Daws Butler, Don Messick, and Mel Blanc), and Penelope Pitstop in The Perils of Penelope Pitstop.

In 2011, Waldo was diagnosed with a benign, but inoperable brain tumor, which eventually led to her death in June 2016, at the age of 96.
