Olivia (also known as Welcome to the World of the Pig Olivia) is a British children's animated television series produced by media company Chorion and based on Ian Falconer's books. The series has won a silver Parents' Choice Award for its positive story lines and characters. The series premiered on 24 January 2009 on Nick Jr. (UK) and aired episodes through August 2013.
Taking place in a world where all people are pigs, Olivia revolves around the title character and her family. The plots are mostly everyday situations in which Olivia finds herself and her unique way of dealing with them. In almost every episode from season 1, Olivia also dispenses her "Rules of Life". In each episode, Olivia dreams of having a job from the episode's experiences, such as being an artist after visiting the art gallery or being her mom's assistant after helping plan her friend's birthday party.
- Olivia (voiced by Jo Wyatt (UK) and Emily Gray (Nick Jr.)), a young pig, is the main character of the show. She is imaginative and fantasizes about different roles, such as pop star or super hero.
