Which actress played Maisie Lockwood in Jurassic World: Fallen Kingdom?

Isabella Sermon played Maisie Lockwood in Jurassic World: Fallen Kingdom.

Maisie is introduced as the young granddaughter of Sir Benjamin Lockwood, John Hammond’s former business partner. She lives at Lockwood Estate and is fascinated by dinosaurs, but her sheltered life changes after her grandfather dies and she discovers the dangerous plan to auction dinosaurs rescued from Isla Nublar.

The film gradually reveals that Maisie’s family history is not what it first appears to be. She was created as a clone of Benjamin’s deceased daughter, Charlotte Lockwood. This makes her story a human counterpart to the franchise’s recurring questions about genetic engineering, identity, and whether scientific ability should be treated as a moral permission slip.

Sermon won the role after approximately 2,500 girls were considered, and the film marked her feature debut. She reprised Maisie in Jurassic World Dominion, where the character is older and living in hiding with Owen Grady and Claire Dearing. A common mix-up is selecting Rafe Spall, Daniella Pineda, or Justice Smith; those actors play adult characters in the franchise, while Sermon portrays Maisie.
