Charlie's Dad is a character in Perks of Being a Wallflower. In the film, he is portrayed by Dylan McDermott.

Charlie's dad first comes across as cold, uncaring, and maybe even abusive. In his first letter, Charlie tells us that his dad slapped him after he made Aunt Helen cry. It's not until his second letter, almost two months later, that he says that his dad "felt terrible for doing it. And he was so sorry. And he would never hit me again. And he hasn't".

He may not ever say "I love you," preferring to express affection with "love pats", but he's a good dad to Charlie, and Charlie even says he's "a very good husband" to his mother.
