The Magic Box, previously known as Uncle Bob's Magic Cabinet, was a magic shop located in Sunnydale.

By late 2000, the shop had changed its name to "Magic Box." That same year, Harmony’s gang killed the owner, Mr. Bogarty, and robbed a book on Slayers. With the owner's death, Rupert Giles bought the shop due to its high profit margins. Soon after opening, Anya Jenkins became a full time employee after demonstrating her knowledge of mystical artifacts and business management. The Magic Box operated as the Scoobies' headquarters, succeeding Rupert Giles' apartment and the Sunnydale High School library.

A training room for Buffy and Giles's sessions was placed in an unused space towards the back of the building. It also contained a trapdoor which led to the sewers.

The Magic Box was damaged and closed in 2001, when Willow, corrupted by grief and magic, fought with Buffy and Giles within it, after draining the magic from its collection of dark magic books. The building was finally destroyed in 2003, along with all Sunnydale.
