Claudia Donovan is a fictional character on the US television series, Warehouse 13 (2009–present), portrayed by Allison Scagliotti. She is the younger sister of Joshua Donovan; she is a computer hacker, inventor, and employee of Warehouse 13.

Claudia Donovan was a little girl when her big brother and guardian, Joshua, tried to do a human teleportation experament with an artifact. It went badly wrong, and he was believed dead. 11 years later, Claudia started to see Joshua, and he was telling her that he wasn't dead. She was so freaked out, she checked herself into a psychiatric hospital. About 6 months later, she then checked herself out.

Claudia blamed Artie for what happened to Joshua, so she proceeded to hack the American power grid in order to find pockets of large unexplained energy usage. Doing so, she managed to locate Warehouse 13 in the badlands of South Dakota, and hacked into its computer mainframe, sending the simple message: KNOCK KNOCK. Shortly after, Claudia arrived at the Warehouse and took Artie hostage using a pair of Supercharged Handcuffs of her own design, capable of delivering a 20,000-volt shock.

She then took Artie to the site of her brother's failed experiment and forced him to help her recreate the conditions that led to Josh's disappearance. When Artie realized that Claudia was, in fact, not insane, he willingly helped in her rescue attempt, using Ben Franklin's Lightning Rod to boost the power of Josh's equipment. Claudia and Artie managed to enter the interdimensional limbo where Josh was trapped, completing the instructions engraved on Rheticus' Compass in order to bring them all back to the corporeal realm.

Claudia Donovan has not been a contender in any CBUB matches.
