Piper Halliwell is a fictional character from The WB television series Charmed, portrayed by Holly Marie Combs. Piper is the middle Halliwell sister in the series, becoming the oldest sister after Prue Halliwell is killed. She and her younger sister, Phoebe Halliwell, soon find out they have a half sister, Paige Matthews, who was the product of their mother's affair with a Whitelighter, thus making Paige half-witch, half-Whitelighter. In Season 3 of the series, Piper marries Leo Wyatt, the Whitelighter assigned to watching over the Halliwell sisters. Their union eventually produces three children: Wyatt Matthew Halliwell, Christopher Perry Halliwell and Prudence Melinda Halliwell. In 2007, AOL named her the 3rd greatest witch in television history, behind Samantha Stevens and Willow Rosenberg.
