Katherine Langford's Biography, Career and Net Worth in 2026

Katherine Langford is an Australian actress with an estimated net worth of $7 million as of 2026. She rose to international fame playing Hannah Baker on Netflix's 13 Reasons Why — a performance that earned her a Golden Globe nomination and established her as one of the most compelling young talents to emerge from Australia. Since then, she has built a diverse career across streaming drama, Hollywood ensemble films, and the West End stage, cementing herself as a genuinely multi-platform performer.

Quick Facts

Early Life and Education

Katherine Langford was born on April 29, 1996, in Perth, Australia, the eldest daughter of Elizabeth and Stephen Langford. Both parents work in medicine — her mother Elizabeth is a pediatrician, and her father Stephen is a doctor with the Royal Flying Doctor Service. Her younger sister, Josephine Langford, also became an actress.

Growing up, Langford showed early creative ambition. She began vocal lessons in 2005, training across classical, jazz, and contemporary styles. At Perth Modern School — a selective public high school — she studied music and drama, was a nationally ranked competitive swimmer, and served as sports captain. She performed in several musical and drama competitions throughout high school.

After graduating, Langford trained at the Principal Academy of Dance & Theatre Arts from 2014 to 2015, then completed a course at Nicholson's Academy of Screen Acting and took part in an actors' residency at the National Institute of Dramatic Art. She had planned to study further at the Western Australian Academy of Performing Arts, but when her career began to take off, she chose to pursue it full-time instead.

Early Film Work

Before her Hollywood breakthrough, Langford appeared in a handful of Australian independent productions: Story of Miss Oxygen (2015), Imperfect Quadrant (2016), and Daughter (2016), the latter of which premiered at the Cannes Film Festival. These early roles gave her on-screen experience but little public profile — that changed dramatically in 2017.

Katherine Langford's Television Career

13 Reasons Why (2017–2018)

Langford's breakthrough came when she was cast as Hannah Baker in Netflix's adaptation of Jay Asher's YA novel 13 Reasons Why. When she landed the role, she had just ten days to secure a US work visa. She prepared extensively for the part, consulting with a sexual assault awareness organization and a psychiatrist specializing in adolescent development to understand the character's experiences.

Hannah Baker is a high school student whose story — told through recorded tapes — centers on the abuse, trauma, and bullying she endured before her death. Langford played the role across the first two seasons, delivering a performance that critics praised for its vulnerability and emotional depth. The series earned her a Golden Globe Award nomination for Best Actress in a Television Series Drama. She did not return for the third season, stepping away from the role in 2018.

The show was not without controversy. Mental health professionals and educators raised serious concerns about its depiction of suicide, and Netflix eventually edited and removed one of the most graphic scenes. Langford handled the debate thoughtfully, supporting the show's intentions while acknowledging the importance of content warnings and mental health resources for viewers.

Cursed (2020–2021)

Langford next headlined the Netflix fantasy series Cursed, an adaptation of the graphic novel by Tom Wheeler and Frank Miller. She played Nimue, a young woman with magical abilities who becomes an unlikely warrior queen leading her people through a holy war. The show co-starred Devon Terrell, Gustaf Skarsgård, and Lily Newmark, among others. Cursed ran for one season before Netflix did not renew it in 2021.

Savage River (2022)

In 2022, Langford starred in the six-part Australian crime drama Savage River, playing Miki Anderson, a woman recently released from prison who returns to her remote hometown under a cloud of suspicion surrounding a murder. The series was produced for Australia's ABC network and co-starred Mark Coles Smith, Robert Grubb, and Nadine Garner.

Katherine Langford's Film Career

The Misguided (2017)

Langford's first film credit was the Australian independent drama The Misguided, which gave her a small role before her Netflix fame.

Love, Simon (2018)

Her first major Hollywood film role came in the 2018 coming-of-age dramedy Love, Simon, based on Becky Albertalli's novel Simon vs. the Homo Sapiens Agenda. Langford played Leah Burke, one of the best friends of Simon (Nick Robinson), a closeted gay teenager finding his way in and out of high school. The film was warmly received by critics and audiences alike and is widely credited as one of the first mainstream Hollywood studio films to center a gay teenage protagonist.

Knives Out (2019)

Langford joined the star-studded ensemble of Rian Johnson's murder mystery comedy Knives Out, playing Meg Thrombey, daughter of Toni Collette's character. The film was a critical and commercial hit, earning an Academy Award nomination for Best Original Screenplay. The cast — which included Daniel Craig, Chris Evans, Ana de Armas, Jamie Lee Curtis, and Michael Shannon — received a Critics' Choice Award nomination for Best Acting Ensemble, and Langford shared in a Satellite Award win for Best Ensemble in a Motion Picture.

It is worth noting that Langford was also cast in Avengers: Endgame, though her scenes were ultimately cut from the final release after test audiences found the sequence confusing.

Spontaneous (2020)

Langford starred opposite Charlie Plummer in Spontaneous, a darkly comic coming-of-age horror film based on Aaron Starmer's novel. She played Mara Carlyle, a teenager navigating romance and life in a high school where students randomly explode. The film was released in 2020 to strong reviews from critics who praised its tone and its two leads.

Katherine Langford's Theater Career

As a teenager, Langford performed in stage productions of Hotel Sorrento and Evita, which gave her a foundation in musical theater long before she became a screen star.

Her first professional theater role came in 2024, when she made her West End debut playing Sally Bowles in Cabaret at the Kit Kat Club — the immersive, award-winning production housed at London's Playhouse Theatre. Langford joined the production on September 23, 2024, performing opposite Olivier Award nominee Adam Gillen as the Emcee. The run concluded on January 25, 2025, a total of approximately 18 weeks. The production — directed by Rebecca Frecknall and widely regarded as one of the finest revivals of the Kander and Ebb classic — won a record-breaking seven Olivier Awards, including Best Musical Revival.

Personal Life

Langford keeps her personal life closely guarded and has not publicly confirmed any long-term romantic relationships. She splits her time between Los Angeles and Perth, maintaining close ties to her family in Australia. Her sister Josephine has carved out her own acting career, most notably in the After film series.

Beyond acting, Langford is a vocal advocate for mental health awareness. She has spoken openly about her own experiences with anxiety, and her platform has allowed her to support young audiences navigating the kinds of difficult experiences depicted in 13 Reasons Why. In February 2025, she signed with talent agency Gersh for representation across all areas.

Social Media

Langford maintains a significant social media presence, with approximately 40 million followers on Instagram (@katherinelangford), making her one of the most followed Australian actresses on the platform.
