Pauline Fowler is a fictional character from the BBC One soap opera EastEnders. She was played by actress Wendy Richard between the first episode on 19 February 1985 and 25 December 2006. Pauline was created by scriptwriter Tony Holland and producer Julia Smith as one of EastEnders' original characters. She made her debut in the soap's first episode on 19 February 1985, and remained for twenty-one years and ten months, making her the second-longest-running original character to appear continuously, surpassed only by her nephew Ian Beale. Since then, she has been surpassed by Letitia Dean who plays Sharon Watts.

The Beales and the Fowlers are a fictional family in the BBC soap opera EastEnders. They were the main family for storylines in early episodes of EastEnders, and remained as such ever since. With at least one member of the family having been a member of the cast from the first episode in February 1985, they are the show's longest serving family. The original Beale/Fowler family consisted of matriarch Lou Beale and her children Pete and Pauline, alongside their families including their children Ian, Mark, Michelle and their spouses Kathy Hills and Arthur Fowler. Additionally, several members of the family have been introduced at a later point, including Pauline and Arthur's son Martin who was the first baby to be born into the show in 1985. The family has been headed with a matriarch first seen with Lou, and over the years, Lou's daughter Pauline, Ian's wife Jane Collins and more recently Pete's wife Kathy, have filled this role.
