Michael Scott (Steve Carell) is the well-meaning but clueless regional manager at Dunder Mifflin. His inappropriate jokes and need for approval often lead to awkward moments, yet his sincerity and childlike desire for friendship make him both cringe-worthy and endearing.

Dwight Schrute (Rainn Wilson) is the eccentric, self-important assistant to the regional manager. His bizarre behavior, intense work ethic, and love for his beet farm make him a memorable character, despite his often over-the-top antics.
Pam Beesly (Jenna Fischer) is the sweet, down-to-earth receptionist who grows in confidence throughout the series. Her relationship with Jim and her journey toward self-discovery are key to her character arc.
Stanley Hudson (Leslie David Baker) is a grumpy salesman who prefers to avoid office drama, often focusing on crossword puzzles. His deadpan delivery and apathy toward Michael’s antics make him a fan favorite.
Phyllis Lapin-Vance (Phyllis Smith) is a warm, motherly saleswoman with sharp wit. Married to Bob Vance of Vance Refrigeration, she provides a calm presence amidst the office chaos.
