Pierre is The Addams Family's stuffed moose head.
He hangs above the fireplace on the living room wall in The Addams Family Mansion. His left antler is pointed downward while the right is up, but they occasionally move, waving at people. His hind quarters are also stuffed and made into a Grandfather Moose Clock so the tail switches on the half-hour and goes all the way around on the hour. This clock is mounted directly across from Pierre so that he can see himself as the world sees him.
Though he appears in most episodes as mere decoration, he is given more screen time in The Addams Family original series episodes:
- "The Addams Family Goes to School"
- "The New Neighbors Meet the Addams Family"
- "Morticia, the Matchmaker"
- "Lurch and His Harpsichord"
- "The Addams Family and the Spaceman"
- "Morticia's Favorite Charity"
- "Uncle Fester's Toupee" - waggles antlers

- "Cousin Itt's Problem"
- "Fester Goes on a Diet"
- "Cat Addams" - waggles antlers to the music
