Jessica Baker (born February 21, 1996) is the eighth child of the Baker family. Her and her twin sister Kim are the first set of non identical twins in the Baker family.

Jessica is seven years old and very close to her twin sister, Kim. She is very smart and starts talking about algebra and math randomly. On her first day at the new school, she is seen holding hands with Kim and Mark. When Jake, Mike and the school bullies get into a fight, Jessica tries to split them up. She is usually seen wearing the same outfit as her twin, although they are not identical. Sometimes she fights with Jake, especially when he stuck a bucket on her head, but they are still very close. She and Jake might fight but they still have a really close bond and care about each other deeply. She shares a room with her sister Kim.

Jessica Baker is played by Liliana Mumy.
