Who is Peppa's best friend?

Peppa’s best friend is Suzy Sheep.

Suzy is a sheep who attends playgroup with Peppa and the other children. The pair are frequently shown visiting one another, playing games, and sharing imaginative activities. Their friendship is one of the most consistent relationships in the series, alongside Peppa’s family connections.

Suzy is sometimes confused with Peppa’s other classmates, including Rebecca Rabbit, Pedro Pony, Emily Elephant, and Candy Cat. Those characters are also part of Peppa’s wider circle, but Suzy is specifically identified as her best friend. The official character descriptions also highlight dress-up as a favourite game for Peppa and Suzy: Peppa commonly pretends to be a fairy princess, while Suzy often plays a nurse.
