Patricia "Pat" Evans is a fictional character in the popular BBC soap opera EastEnders. She has been played by Pam St. Clement since 12 June 1986, just over a year after the show first aired. Pat was also played by Emma Cooke in a soap 'bubble' Pat and Mo: Ashes to Ashes, delving into the her past with sister-in-law Mo Harris, which aired in 2004.

Pat is a tough enemy, a good friend, a straight talker and a woman who won't be messed with. She's had a rough life and made many mistakes, but she's a survivor and she refuses to let her past grind her down. Pat has so far been married four times, making her the most-married character in the whole of EastEnders, until 2007 when Ian Beale completed his fourth marriage to Jane Collins.
