Seraphina Beh-Moore (born 1994) is an English actress. After beginning her career in various stage productions, she initially gained attention for her role as school bully Madison Drake in the BBC soap opera EastEnders (2017). She has since appeared in various British television series including Top Boy (2019, 2022), Quiz (2020), Crongton (2024) and Malpractice (2025), as well as continuing to appear in stage productions.
Beh was born in 1994 in Croydon, London, to a family of African descent. She attended St Mary's Catholic High School in the area; whilst there, she made news headlines for successfully campaigning to get a 140-year ban on girls wearing trousers lifted. When it was lifted, she said: "I am proud that we have won this battle for generations of schoolgirls in the future." She competed on a basketball team whilst at school, but has stated that she was the worst one on her team.
Whilst attending St Mary's, Beh went on a school trip to the Young Vic to watch The Brothers Size. She felt inspired as a Black woman, stating: "it was the first time I thought I could see myself as a woman of colour doing [acting]". Prior to this, she noticed a pattern of Black people predominantly portraying gang members and criminals, which she could not relate to at all.
After she had completed her A levels, Beh began attending various open auditions, and in 2012, she made her stage debut in a production of Skeen at the Ovalhouse. She continued making various stage appearances and eventually booked her first television role in an episode of the BBC medical drama series Casualty in 2014. Beh then went to train with the National Youth Theatre Company (NYTC). Whilst there, she auditioned for the role of Madison Drake on the BBC soap opera EastEnders. Her final recall for the role landed on the same day as her final performance of Pigeon English, a production with the NYTC. She assumed she would be unable to attend, but the producers of EastEnders instead came to the production to see her; she subsequently landed the role of Madison and left the NYTC early to pursue the job. Beh's character was brought in alongside Alexandra D'Costa (Sydney Craven) and the pair acted as bullies towards characters Louise Mitchell (Tilly Keeper) and Bex Fowler (Jasmine Armfield). The characters were written out after they are charged with GBH for pushing Louise onto an array of lit candles. For her portrayal of Madison, Beh won the International Achievement Recognition Award for Best Emerging Actress.
After her EastEnders role in 2017, Beh starred in a production of Parliament Square at the Royal Exchange and the Bush Theatre. 2018 saw Beh appear in Leave Taking, also at the Bush Theatre, where her performances was praised by The Guardian, as well as a production of The Wolves at Theatre Royal Stratford East. She then appeared in an episode of the BBC medical drama series Holby City in 2019. That same year, she joined the cast of the Netflix series Top Boy for its third series. She portrayed Farah, a character she returned as for its fourth series in 2022. In 2020, she appeared in two episodes of the crime drama series Silent Witness, as well as a main role in the ITV1 miniseries Quiz. She also appeared in the third series of Bard from the Barn. In 2023, Beh made her film debut in Polite Society. 2025 then saw her star in the BBC Three comedy series Crongton, as well as appearing in the second series of the ITV1 medical drama series Malpractice.
