"Queen Vic Fire Week" is a group of four episodes of the BBC soap opera EastEnders, broadcast between 6 and 10 September 2010 on BBC One. The episodes included a fire at The Queen Victoria public house, also known as The Queen Vic or The Vic, and the departure of the character Peggy Mitchell, portrayed by Barbara Windsor, who left the series after sixteen years in the role. During the episodes, Peggy—the pub landlady—has her crack cocaine-addicted son Phil imprisoned in The Queen Victoria, forcing him to go cold turkey. She later learns that her deceased husband Archie was murdered by the person he raped: Stacey Branning. Before she can report Stacey to the police, Phil escapes and sets the pub on fire. Stacey and her infant daughter Lily are trapped inside, but are rescued by her lover Ryan Malloy – prompting Stacey to reveal to him that he is Lily's father. In light of the incident, Peggy decides against reporting Stacey for Lily's sake. She then plans to make a fresh start, bidding her family goodbye and leaving Walford.

Within eight months of the show's original launch, it had reached the number one spot in BARB's television ratings, and has consistently remained among the top-rated series in Britain. Four EastEnders episodes are listed in the all-time top 10 most-watched programmes in the UK, including the number one spot, when over 30 million watched the 1986 Christmas Day episode. EastEnders has been important in the history of British television drama, tackling many subjects that are considered to be controversial or taboo in British culture, and portraying a social life previously unseen on UK mainstream television.
