Milly Alcock Net Worth

Milly Alcock has an estimated net worth of $2 million, according to Celebrity Net Worth, Milly Alcock net worth page (figures as of July 6, 2026).

Milly Alcock is an Australian actress who was raised in the Sydney suburb of Petersham. She discovered acting as a young child playing Little Red Riding Hood in a school show, and she later attended Newtown High School of the Performing Arts, leaving in 2018 when she was cast in the comedy-drama Upright.

She made her television debut in a 2014 episode of Wonderland and presented short-form shows on Disney Channel in Australia. Her role as runaway teenager Meg in Upright earned her an AACTA Award nomination, making her one of the youngest nominees in the category.

From House of the Dragon to Supergirl

Alcock's big break came in 2022, when she played young Princess Rhaenyra Targaryen in HBO's House of the Dragon, the Game of Thrones prequel. Critics singled her out as a highlight of the early episodes, and she earned a Critics' Choice nomination. A role in one of the world's most-watched shows put her in front of a global audience.

She then made her West End stage debut in The Crucible in 2023 and starred with Julianne Moore and Meghann Fahy in the Netflix limited series Sirens in 2025.

Her biggest step came when she was cast as Kara Zor-El, or Supergirl, in the new DC Universe. She made a brief uncredited appearance in Superman in 2025 and then led her own film, Supergirl, in 2026. Leading a superhero film usually brings a large jump in pay and a contract for future appearances.

Her early commercial and presenting work in Australia gave her experience on camera long before her breakout.
