Tanya Moodie is a Canadian actress and producer, best known for her work on Motherland, The Clinic, and her many stage credits, which include productions with the Royal Shakespeare Company, the Royal Court Theatre, the National Theatre and the Théâtre des Bouffes du Nord.

Tanya Moodie was born on 16 April 1972 in Ottawa, Canada, to Jamaican parents. She moved to England at the age of 17, when she was offered a place at RADA, where she was later employed as an associate teacher and council member.

Moodie's first television role was in the comedy So Haunt Me in 1994, followed by a starring role as Hunter in Neil Gaiman's 1996 fantasy mini-series Neverwhere (1996). She featured in guest roles in various series in the 2000s, and in 2008–9 had a regular role in Irish medical drama The Clinic. She also played the role of John Watson's therapist Ella Thompson in Sherlock.

In 2016 she played Gertrude in Simon Godwin's production of Hamlet for the Royal Shakespeare Company.

From 2019, Moodie starred as Meg in the BBC comedy series Motherland. In a 2021 interview with the Huffington Post, Moody shared that she was proud of the feedback she had received about her character's cancer storyline: "There’s been people who have written me very personal messages saying that they’re going through [cancer] right now or their parents are, and they say we’ve really shown what it’s like. I’m really happy that that’s happened – I didn’t expect it to. I didn’t finish filming and say ‘I really feel like I’ve nailed what it’s like to go through this journey’, because it’s so subjective and unique to people."

In 2020, Moodie starred in the third series of Tin Star as Catherine Mckenzie. The series was created by Rowan Joffé.

In April 2022, Moodie featured as Regina in series 1 episode 4 of Ten Percent. Moodie appeared in Sam Mendes' film Empire of Light, released in the US in December 2022, and the UK in January 2023. Moodie appears alongside Olivia Colman, Colin Firth and Micheal Ward. Also in December 2022, Moodie reprised her role as Meg in the Christmas special of Motherland, titled "Last Christmas". The episode garnered wholly positive reviews from critics.

In March 2023, Moodie appeared as Serena in two episodes of the Cash Carraway-created Rain Dogs.
