"Morgan, long time no see." "Yeah. That was the longest time out I've ever had."
— Cory & Morgan Matthews
Morgan Matthews is the younger sister of Cory and Eric, the older sister of Joshua, and the only daughter to Amy and Alan. Mainly used for comedic purposes, the character of Morgan is usually annoying to Cory, and seems closer to Eric. She was initially played by Lily Nicksay, but was replaced by Lindsay Ridgeway in season 3. Throughout the series, it becomes clear that Morgan is a good singer, as shown in Better Than the Average Cory and Shallow Boy.
