Larry and museum exhibits including Pharaoh Ahkmenrah (Rami Malek), Teddy Roosevelt (Robin Williams), Attila the Hun (Patrick Gallagher), Sacajawea (Mizuo Peck), Roman centurion Octavius (Steve Coogan) and Jedediah (Owen Wilson) wind up at the British Museum's famed Egyptian wing to solve the deadly mystery.
In 1938 Egypt, a team of archaeologists discover the tomb of pharaoh Ahkmenrah, including a young Cecil Fredericks, finding the magical Tablet of Ahkmenrah. The locals warn the group that removing the tablet will end its magic.
In present day New York City, Larry Daley remains the night guard of the Museum of Natural History. He and the exhibits, brought to life each night by the tablet, help re-open the Hayden Planetarium. A new wax Neanderthal resembling Larry named Laaa is introduced, identifying Larry as his father. Ahkmenrah shows Larry that the tablet is corroding, which later causes the exhibits to act erratically, causing mayhem at the planetarium’s reopening. Larry catches his son Nickolas Daley throwing a house party, who plans on taking a gap year to sort out his life.
Larry reunites with Cecil, now in retirement, who realises the end of the tablet’s magic will cause the exhibits to become lifeless. Cecil explains Ahkmenrah's parents, Merenkahre and Shepseheret, may be able to restore the tablet’s power, but are located in the British Museum. Larry convinces the museum’s curator, Dr. McPhee, to let him ship Ahkmenrah to London to restore the tablet, convinced that Dr. McPhee knows its secrets. Larry and Nick travel to the British Museum, bypassing the night guard Tilly. To Larry’s surprise, Theodore Roosevelt, Sacagawea, Ahkmenrah, Jedediah, Octavius, Dexter, and Laaa have come as well. Laaa is left to stand guard while the others search the museum, the tablet bringing its own exhibits to life.
They are joined by a wax Sir Lancelot who helps them fight off the aggressive museum exhibits like a Xiangliu statue and a Triceratops skeleton. Jedediah and Octavius fall through a ventilation shaft, but are rescued from a Pompeii model by Dexter. The group find Ahkmenrah parents, learning the Tablet of Ahkmenrah’s power can be regenerated by moonlight, since it is empowered with the magic of Khonsu. Lancelot mistakes the tablet for the Holy Grail and steals it, leaving to find Camelot. Larry and Laaa are locked in the employee break room by Tilly but escape, Laaa remaining behind to distract Tilly, but they become attracted to each other.
Lancelot crashes a performance of the Camelot musical, starring Hugh Jackman and Alice Eve as King Arthur and Queen Guinevere, but Larry and the others chase him to the theatre roof, where the New York exhibits begin to die. Lancelot then sees that the quest was about them and gives the Tablet of Ahkmenrah back. The moonlight restores the tablet’s power, saving the exhibits. They decide that Ahkmenrah and the Tablet should stay with his parents, even if it means the New York exhibits will no longer come to life. Back in New York, Larry spends some final moments with his friends before sunrise.
Three years later, Larry now works as a teacher, and a travelling British Museum exhibit comes to New York. Tilly becomes the new night guard, and gives the Tablet of Ahkmenrah to Dr. McPhee, showing him its power, and allowing the exhibits to awaken again. Akmenrah was there as well because either he came back to visit the Museum of Natural History one last time and then go back to the one in London afterwards or his Egypt room was upgraded and changed to make room for Shapsheret and Makenkere's tombs as well. Outside, Larry watches them party inside.

Ben Stiller admitted that a sequel was "a possibility" and on January 22, 2010, co-writer Thomas Lennon said to Access Hollywood, "That after the success of two Night at the Museum films, it's no surprise that 20th Century Fox is looking to develop a third and that those suspicions are indeed true and how could you not? I think it's a really outstanding idea to do 'Night at the Museum 3,' in fact," he said. "I wonder if someone's not even already working on a script for that," he added with a raised eyebrow. "I cannot confirm that for a fact, but I cannot deny it for a fact either... It might be in the works." In an interview, Stiller confirmed the sequel, however, he said that it was only in the "ideas stage".
