Jim Halpert — played by John Krasinski — works in Sales. Professionally, he's a valued employee who has received a couple of promotions during the show's first three seasons, becoming most recently the Number 2 Man at the branch of Dunder-Mifflin managed by Michael. An ongoing story arc for the series is the relationship between Jim and Pam, the receptionist. Jim once confided in Michael about his romantic feelings for Pam, but finally, after revealing his true feelings and kissing her in the episode "Casino Night", concluded Pam would marry Roy, and decided to take a promotion and transfer to another branch. Later, when his new boss abandoned the company, Jim was made the Number 2 Man at the Scranton Branch. Jim has rallied his coworkers for an Office Olympics competition, and invited them to a party at his house (in the episode "E-mail Surveillance"). In the episode, "The Merger", he said to Pam that he was currently seeing someone. It was hinted in "The Merger", and then was confirmed in "The Convict" that he was seeing Karen Filippelli He loves practical jokes, especially on Andy or Dwight.

 

Pamela Beesly — played by Jenna Fischer — is the sweet office Receptionist bearing the brunt of Michael's awkward behavior. She sometimes protects Michael from his own bad habits; in one episode, "Casino Night", she demonstrated how she improved Michael's phone etiquette by not transferring calls to him right away, pausing to allow him to get a joke out of his system. Pam began the series engaged to warehouse worker Roy; the engagement continued for two full seasons until days before their wedding, Pam broke off the engagement. Pam enjoyed former co-worker Jim's attention, and together they brainstormed malicious pranks to play on Dwight. Rumors of Jim and Pam's flirtations circulated through the office at times. After having feared the prospect of winning another "World's Longest Engagement" award, Pam was relieved to win the "Whitest Sneakers" award at the 8th annual Dundie Awards. Her favorite flavor of yogurt is mixed berry. She dislikes country music, competitive frisbee, hunting, high-pitched male love ballads, and Pig Latin

Dwight Kurt Schrute — played by Rainn Wilson — is a pretentious, megalomaniacal, socially awkward Assistant (to the) Regional Manager and honorary branch Security Advisor. He has a severe superiority complex, and insisted his job title made him the de facto "Assistant Regional Manager", even before being given that title. Dwight craves authority, and relishes any minor task that he is given that allows him to give orders to the other employees; he often assumes authority even when it is not handed to him. Dwight lives on and operates a beet farm with his cousin. Dwight enjoys paintball, anime (he is seen wearing a shirt with the name of an anime convention printed on it in seasons one and two), has a purple belt in karate and is as dedicated to his sensei as he is to Michael, to whom he commonly sucks up despite his boss's degrading comments. As of the second season, Dwight and Angela have been secretly dating. Dwight is a target of practical jokes orchestrated by Jim and Pam.

Ryan Howard — played by B.J. Novak — is a competent, quiet, young Sales Representative who started as a temp and is usually a step ahead of his co-workers. He attends business school at night, and arguably knows more about business than his boss. He feels quite uncomfortable around many of his co-workers, but unwittingly began a relationship with Kelly Kapoor, when the pair hooked up on the eve of Valentine's Day. Michael, who stated in a game of "Who'd You Do?" that he would have sex with Ryan because he is going to own his own business, appears to have a "man-crush" on Ryan and named him "Hottest in the Office" at the 8th Annual Dundie Awards. Try as he might to avoid doing so, Ryan often finds himself being assigned such tasks as being Todd Packer's designated driver and retrieving childhood videotapes from Michael's mother's house. Ryan earned himself the nickname of 'the fire guy' after he accidentally left some food in the toaster oven and started a fire in the office.

Angela Martin — played by Angela Kinsey — Accounting Supervisor. A judgmental, homophobic, pious individual, Angela is head of the accounting department and a safety officer. She despises Will and Grace — excepting those episodes with appearances by Harry Connick Jr. Though she is a constant source of complaints to Human Resources, she redacts those lodged against Dwight, who calls her "monkey", at the onset of their secret romance. She had a bobble-head doll made in Dwight's likeness as a Valentine's Day gift, and received a key to his house in return. Angela secretly follows Dwight to the office supply convention in Philadelphia under the name Jane Doe. Angela lives with several cats, displays posters of infants posed as adults, is a vegetarian and a singer, and believes orange to be a "whorish" color. Angela bottles up her emotions to the point that on occasion she has private, emotional outbursts over relatively trivial matters. Angela refuses to accept the "Tight Ass" award at the 8th Annual Dundie Awards. Angela hints she has a crush on Roy and admits she would choose Roy over Jim if pressed on the matter. She claims to weigh ninety pounds.

Oscar Martinez — played by Oscar Nuñez — Accountant. Oscar is an American-born Latino of Mexican descent, whose parents emigrated from their home country. He plays a paper football game (called Hateball) with Kevin whenever Michael isn't around and keeps a two-year running total of their scores. Oscar enjoys ice skating, likes the office thermostat to be set to a chilly 66 degrees, and claims to be more offended by Angela's kitschy posters featuring infants posed as blues musicians than by hardcore pornography. Oscar is gay and lives with his partner, Gil. The pair go on a three-month vacation to Europe on Dunder-Mifflin's tab with exclusive use of the company car, as consideration for his agreement to forbear from suing the company after Michael publicly outs Oscar in the season three premiere. He wins the "Show Me The Money" award at the 8th Annual Dundie Awards.

Kevin Malone — played by Brian Baumgartner — Accountant. Kevin is bald, overweight, slow-witted, and seems to have just two facial expressions: a scowl or an impish grin. He is typically quite subdued with his humorous hangdog face. A Detroit Pistons fan, Kevin has shown a talent for basketball, paper football office game called "Hateball", and "How Many M&M's Can You Put In Your Mouth?" His favorite number is known to be 69 in reference to the the sexual position. Kevin is engaged to a woman named Stacy, who has a daughter named Abby. Kevin plays drums and is also the lead singer in a local tribute band. The group initially was a Steve Miller Band tribute called Jokers and Tokers, but recently refocused on the music of The Police, and rebranded accordingly as "Scrantonicity," an homage to Synchronicity. Kevin wins the "Don't Go In There After Me" award at the 8th Annual Dundie Awards. In 2002, Kevin won the $2,500 No Limit Deuce to Seven Draw Tournament at the World Series of Poker in Las Vegas.

Creed Bratton — played by Creed Bratton — Quality Assurance. A taciturn quality assurance representative, Creed lives in Toronto, spending three nights a week there in order to milk the welfare state. The remainder of the week he sleeps in his cubicle, using the office water cooler to bathe. Creed is older than all of the other employees and was originally hired by Dunder Mifflin in the late 1980s, when Ed Truck was still regional manager. Creed spent time in an iron lung as a teenager, was a member of The Grass Roots, and once toured with Cream and Janis Joplin. Following his rock career, he had his own radio show in the 1970s as DJ Wacky Weed Creed. He has concentration problems due to his drug use during his rock career and is unfamiliar with many of his coworkers. Creed has four toes on his right foot (losing one because his parents bound his feet as a young child) and enjoys arcade-style light gun shooting games. He speaks semi-fluent Chinese and has friends in Hong Kong. He can identify strains of cannabis in high-resolution photographs and snacks on nutritious, fragrant mung bean sprouts he keeps stashed in his desk on a damp paper towel, though he admits "they smell like death." He casually admits a passion for stealing without a care. In the episode "Branch Closing" he expands on this by selling $1200 worth of office equipment when he thinks his branch is closing. Creed once saved his job by convincing Michael to fire Devon instead. Until Casino Night, Creed never owned a refrigerator.

Stanley Hudson — played by Leslie David Baker — Sale Representative. Hudson is a serious, hardworking employee, who dislikes Dunder-Mifflin and believes he is underpaid. In fact, he is overjoyed when he hears that the office may shut down in "Branch Closing", because the pay he would receive from the severance package would be enough to allow him to retire. One of the highlights of Stanley's work-year is Pretzel Day. Stanley only thinly attempts to hide his disgust and disrespect for Michael, who tends to make inadvertently offensive remarks to Stanley based on racial stereotypes, such as expecting Stanley to be a good basketball player. Stanley generally prefers working on crossword puzzles during the various staff meetings rather than giving his undivided attention to Michael, thus giving him the nickname "The Crossword Puzzle Guy". He has two children, one known to be his child from a previous marriage. He won the "Great Work" award at the 7th Annual Dundie Awards, and didn't know what to make of the "Fine Work" award he won the following year. While very serious, even Stanley does come around such as in the Office Olympics, when he becomes a participant, despite telling Jim earlier that his office game is "Work real hard so my kids can go to college." When generally bored and unhappy (particularly involving Michael), Stanley simply props his elbows on a table and rests his face between his hands to protest his boredom. Until the merger, Stanley was the only African-American employee and was annoyed by Martin Nash's attempt to befriend him. He is extremely protective of his daughter, threatening violence against anyone who he believes to be flirting with her.

Phyllis Lapin — played by Phyllis Smith — Sales Representative. Phyllis is an introvert motherly type often mistaken as older than her age. She is often insulted and embarrassed by former classmate Michael and is the target of many of his crude jokes, but like the rest of the staff, she tolerates his behavior. However in Gay Witch Hunt she insults Michael by telling him that everyone thought he was gay in high school, and proves she can be witty at times. Phyllis often is the first to offer her services when a volunteer is requested by happily saying "I'll do it". She loves "girl talk" and gossip and believes herself to be closer to her co-workers than she really is. Phyllis serves on the party planning committee where she often butts heads with hypercritical Angela. She is engaged to Bob Vance of Vance Refrigeration.. She wins the "Busiest Beaver" award at the 8th Annual Dundie Awards, although, due to an error, her statue lamentably reads "Bushiest Beaver". Phyllis admits that if she could sleep with one person in the office, it would be Jim. Phyllis also shocks the room during a "sexual harassment" seminar, by asking if one-night stands are included in a rule requiring reporting office romances to human resources.

Meredith Palmer — played by Kate Flannery — Customer Service/Purchasing/Accountant. Meredith is a twice-divorced, quiet, red-haired woman and an alcoholic who doesn't like the office lights on in the morning. When drunk, she has a tendency to come on very strong to men around her. Palmer joined Alcoholics Anonymous in the second season and attempts to follow through on New Year's resolutions to quit drinking (on weekdays) but never succeeds. Her divorces and her hysterectomy both have been mocked by Michael. Meredith drives a Ford Aerostar minivan and has custody of her son, Jake, with a history of troublemaking, while her ex-husband has custody of their good daughter Wendy. She is allergic to dairy products. She is also once caught eating Angela's waterless hand sanitizer. She wins the "Grace Under Fire" award at the 7th Annual Dundie Awards. Michael makes the entire office throw a month-early birthday party for Meredith in the first season in hopes of relieving the stress from downsizing rumors.
