Seth Plummer is a 12-year-old boy from the 2005 live-action comedy The Pacifier. He is portrayed by Max Theriot.

Personality
Seth is kind of stressed when Wolfe annoys him with his rules, when at first hates him. Most of the time, he is confident enough to sing "Sixteen Going on Seventeen" on stage.

Role in the film
Seth is first seen coming downstairs with Zoe to meet Wolfe. He reappears holding Peter's hand when Julie kisses and hugs the kids goodbye. He is briefly seen again whe Wolfe strictly tells him to go to bed, but Seth rudely replies, "Bite me." He is seen the next morning when Wolfe wakes him up with his whistle. He tells Seth to get a move on, but Seth calls him insane and flops back down, and Wolfe flips the bed over. When Wolfe notices that Seth is gone, Zoe tells him that he is in his room, and Wolfe runs upstairs to it. No answer comes from the room, so Wolfe breaks down the door with his foot, which shocks Seth when he comes from the bathroom. Wolfe then straps a watch on Seth's wrist and leaves.

Seth is later seen with his siblings in the living room, and stands up holding Peter and reminding Wolfe that he has wrestling practise tomorrow, with his siblings protesting to Wolfe.
