Louise Mitchell (also Fowler) is a fictional character from the BBC soap opera EastEnders, who has been played by four different actors since her on-screen birth on 6 November 2001. Louise has been played by Rachel Cox between 2001 and 2003, Danni Bennatar in 2008, Brittany Papple in 2010, and Tilly Keeper in 2016 to 2020. Keeper's casting was announced on 16 December 2015 and she made her first appearance as Louise on 15 January 2016. The character's departure was announced in December 2019, with Louise making her last appearance on 24 January 2020. Louise is a member of the Mitchell family and briefly part of the Fowler family. She is the daughter of Phil Mitchell (Steve McFadden) and Lisa Shaw (Lucy Benjamin), stepdaughter of Sharon Watts (Letitia Dean), granddaughter of Peggy Mitchell (Barbara Windsor) and the half-sister of Ben Mitchell (Charlie Jones/Harry Reid/Max Bowden). Louise's early storylines include Lisa lying about her paternity; her nearly being killed in a road collision caused by Phil's archenemy Steve Owen (Martin Kemp); subsequently becoming caught up in her parents' relationship; and a feud with Ben that involves him physically torturing her. From her return in 2016, Louise's storylines included her blackmailing Abi Branning (Lorna Fitzgerald) over her fake pregnancy; helping her father cope with the death of his mother Peggy; forming a friendship with Bex Fowler (Jasmine Armfield); being the victim of bullying by Alexandra D'Costa (Sydney Craven) and Madison Drake (Seraphina Beh), in the early midst of which Louise briefly bullied Bex. After the bullying storyline ended with Louise suffering burns in her prom disaster, Lisa made a brief return to the series and appeared to have abducted Louise – albeit this was part of the feud between Lisa and Phil. In addition, Louise's storylines have also included being kidnapped by a gang that are in dodgy dealings with Ben and Phil and relationships with fellow student Travis Law-Hughes (Alex James-Phelps); Steve's son Hunter Owen (Charlie Winter); local classmate Keegan Baker (Zack Morris) and Phil's employee Keanu Taylor (Danny Walters), which results in the birth of their daughter Peggy Taylor. Louise played a pivotal role at Christmas 2019 when she discovered that Keanu had been sleeping with her stepmother Sharon Mitchell (Letitia Dean) and is the father of her unborn child. After leaving Keanu for dead, Louise departed to Portugal with Lisa and Peggy to escape imprisonment.
