Good Luck Charlie is an American family television sitcom airing on Disney Channel in the United States.

The series was created by Phil Baker and Drew Vaupen, who wanted to create a program that would appeal to entire families, as opposed to children only.

It revolves around the Duncan family as they try to adjust to the birth of their fourth child, Charlotte "Charlie" Duncan (Mia Talerico).

In each episode, Teddy Duncan (Bridgit Mendler) creates a video diary containing advice for Charlie about their family and life as a teenager.
