One of the central elements of Jim Halpert's character as originally conceived is his devotion to playing pranks at the office to relieve boredom.
By far, his most common target is his overbearing desk mate, Dwight Schrute, though he later moves on to playing pranks on Stamford co-worker, Andy Bernard, when he transfers branches. He will sometimes prank another coworker, such as the unsuspecting Kevin, if thrown into an awkward situation or bored. More often than not, Pam Halpert collaborates with Jim on the pranks on Dwight.
Here are some of the more notable pranks Jim has played on Dwight, Andy, or any other unsuspecting co-worker. A few of them are Dwight's pranks too.
- Encased Dwight's stapler in Jell-O ("Pilot").

- Tricked Dwight into believing he was being recruited by the CIA and made him destroy his cell phone ("A Benihana Christmas").

- Scared Dwight by sending him a scream video. It seemingly backfired when Dwight knew what it was, but as he watched it anyway Jim popped up next to him in a mask ("The Surplus", deleted scene).

- Adds 5 keys to Dwight's key ring but the prank fails after Pam laughs. Jim's full plan was to slowly add an obscene amount of extra keys to Dwight's key ring just a few at a time. Eventually, he would cause Dwight's pants to fall down ("Nepotism").

- Pushed Dwight off a stool he was secretly sitting on, after Dwight claimed he would constantly stand at work to increase productivity. Jim had also pulled money out of Dwight's wallet and thrown it on the floor, knowing Dwight couldn't pick it up, and publicly praised Dwight's intention to never sit again, making it impossible for Dwight to sit in front of his co-workers ("Mrs. California").
- Tricked Dwight into believing he'd been recruited by the CIA two additional times. (see above) ("Christmas Wishes")
- Attempting to trick Dwight into playing a prank on him by letting Dwight overhear his credit card number and security number (Andy had threatened to give both of their Christmas bonuses to the victim if either of them pulled a prank on the other). This failed when Dwight used the credit card number to send flowers to Pam in Jim's name ("Christmas Wishes").
- Attempted to frame Dwight for defacing a picture of his daughter. This backfired when Andy pointed out this was a fireable offense, prompting Jim to half-admit he'd done it ("Christmas Wishes").

- Switched Dwight's suit with a tear-away Velcro version while at the dry cleaners, then tore it off of Dwight in the Dunder Mifflin parking lot, leaving Dwight in his underwear for his co-workers to see ("Free Family Portrait Studio").
- Convinced Dwight that Clark is a better Dwight than he is. Jim tried to convince Dwight that Clark has a belt higher than a black belt ("New Guys").
- A man dressed like Jim, claiming to be Jim and everyone else believes is Jim takes Jim's place. Jim and Pam's actor friend, Steve, pretends to be Jim while Jim is at the dentist. Steve is Asian and pretends that he has been Asian the whole time and Dwight just never noticed. Steve knew everything Jim knew including his sales history and his password to access his messages. He also replaced his own family photos with ones of Pam, Steve, and two Asian children ("Andy's Ancestry").
- Convinced Dwight that electromagnetic radiation causes infertility. Jim placed a bag of popcorn with only one kernel popped under Dwight's chair hoping that Dwight will believe the poorly insulated wiring is what caused it. He convinces Dwight to shut down the building ("Work Bus").
- Tricked Dwight into believing he was on a radio talk show. Jim, Pam, Nellie, and Darryl tricked Dwight into believing he was on a radio talk show to talk about Dunder Mifflin. Dwight seems confident and tells them that he is basically the CEO as David Wallace is very "hands off" and lets Dwight run the company. They trick him into taking off his shirt and pants by telling him the buttons on his clothes are making noise that is interfering with the audio on the "radio show." The four then play different "experts" and make Dwight believe that the paper is dangerous and the stock is plummeting. Dwight, unable to answer to all these troubles, starts blaming David Wallace. The four then make Dwight believe that David Wallace has become insane and kidnapped a mailman and is holding him hostage. The prank nearly backfires when Dwight actually calls David. David however ignores Dwight and hangs up ("The Boat").
- Sent Dwight (and unwittingly the entire office, except Pam) on a quest for "the Holy Grail", using a series of clues called "The Dunder Code" which Robert Dunder had supposedly left in the office years ago. The prank had been laid by Jim around 2005–2006, who subsequently forgot about it. By the time Dwight found the clues, years later, with the staff joining in, the grail had been found by warehouse worker Glenn, who was using it as a coffee mug ("Customer Loyalty").
- Convinced Dwight that he was in the Matrix. He trained a cat to run through the ceiling to create the illusion of it appearing twice, and thus a glitch in the Matrix, hired various actors and workers from the office to further convince him, before having Hank (masquerading as Morpheus's brother, Borphius), offer him the blue or red pill, like in the movie. This backfires when Dwight reveals that he's completely happy with his life, and wouldn't leave it for anything. Pam is touched but Jim is disappointed, before rushing to him after realizing the blue pill is not safe to swallow ("Finale", deleted scene)
- Told Dwight that he couldn't be his bestest mensch because he had to be older than him. He reveals that he called Michael to come in from Colorado to be his true bestest mensch. Simply the "Best Prank Ever" (Also, the last) ("Finale").
- Called Dwight as a concerned citizen to complain about how "loud" Dunder Mifflin paper is (Where Are They Now?)
List of pranks pulled by others
In a few cases, others have pulled or attempted pranks.

An unsettled Daryl decided to quit pranking for good ("The Cover-Up").
- Pam, with Kevin's help, rearranged the elevator buttons to prank Dwight, to make up for accidentally ruining Jim's key prank (see above). This backfired when they both became stuck in the elevator and Dwight (who had been drinking excessive amounts of water) began urinating in the corner ("Nepotism").

- In a deleted scene from "Finale", it is revealed that Jim pulled so many pranks on camera that he had to speak at various schools telling kids not to be like him.
