Erin Doherty

Doherty is of Irish heritage and from Crawley, West Sussex. Doherty's parents divorced when she was 4 and she began acting in Sunday drama classes with her older sister Grace shortly after. She studied at Hazelwick School in Crawley, where she grew up. A talented footballer, Doherty played in midfield for and captained the Crawley Wasps and was scouted by Chelsea Women; she reached the age where she "had to commit" to either football or acting and chose the latter.

Doherty took a one-year course at the Guildford School of Acting (2011–12) before training at the Bristol Old Vic Theatre School (2012–15).

Whilst training, Doherty won the Stephen Sondheim Society Student Performer of the Year Award (SSSSPOTY) in 2015 for her rendition of "Broadway Baby" from the Sondheim musical Follies.Doherty's first television appearance was in a 2016 episode of Call the Midwife, followed by a role in the 2018 BBC miniseries Les Misérables.

In 2018, Doherty was a Screen International Star of Tomorrow, and an Evening Standard Rising Star.

In 2019, Doherty appeared as Princess Anne in the third season of The Crown. She knew little about the princess before being cast, and consequently spent hours studying Anne's family history and life. Doherty made a point of only watching footage of the princess at the age she was portraying her, rather than interviews of Anne in later life. Anne's voice is very different from Doherty's, being much lower in pitch; the actress spent time carefully learning and mimicking it, finding that it "was the key into her psyche". Doherty reprised her role as Princess Anne in the fourth season of the series.

In 2022, Doherty is the protagonist in the BBC/Amazon Prime drama Chloe alongside Poppy Gilbert as Becky. She was also cast to portray Anne Askew in the psychological horror film Firebrand in 2023.

In 2024, she played Clare a missing child returning to her parents aged 24 in the British psychological thriller film Reawakening, alongside Jared Harris and Juliet Stevenson.
