Hannah Phillips is Sid's 6-year-old little sister. She cherishes her dolls and holds pretend tea parties with them. Her toys are often the victims of Sid's activities. She gives the name "Mrs. Nesbit" to Buzz when she dresses him for a tea party after discovering him. She appears to have crossed eyes. She is voiced by Sarah Freeman. When Sid becomes frightened of toys, Hannah capitalizes on it by shoving Sally into his face and chasing him into his room, saying "What's wrong, Sid?! Don't you wanna play with Sally?!"
