Judy Hensler is a fictional character in the American television sitcom Leave It to Beaver.

In one episode, she believed Beaver was Miss Canfield's pet and urged him to prove her wrong by putting a spring-action snake in the teacher's desk drawer.

In another episode, Beaver begged his parents to buy him a sweater in a shop window.

Judy's parents were seen briefly in an episode about Beaver's selection to perform in a school play as a canary.

The character was eventually dropped and replaced by Penny Woods, who became Beaver's new nemesis.
