Megan Griffin is a fictional character in the animated television series Family Guy. Meg is the eldest child of Peter and Lois Griffin and older sister of Stewie and Chris, but is also the family's scapegoat who receives the least of their attention and bears the brunt of their abuse. She is often bullied, ridiculed, and ignored. Originally voiced, unbilled, by Lacey Chabert during the first season, Meg has been voiced by Mila Kunis since season 2.
