Charles "Charlie" Kelly is a fictional character and the main protagonist on the FX series It's Always Sunny in Philadelphia, portrayed by Charlie Day. Charlie is co-owner at Paddy's (although he later sells his shares) and a childhood friend of Mac and Dennis. He is also Frank's roommate and possibly his biological son. He is addicted to huffing various glues and paints, and also does not know how to read or write.

Charlie is an easily excitable man-child who is unable to cope with daily problems, prone to emotional outbursts and is often confused and flabbergasted by modern-day life. His anger management issues, substance abuse, poor hygiene, lack of common sense, and a poor grasp of reality tends to prevent him from ever achieving much success in life, and he instead lives in squalor. He frequently abuses inhalants such as glue, spray paint and poppers and, like the rest of the Gang, is a heavy drinker. He also frequently eats cat food before bed, to induce a feeling of sickness that allows him to fall asleep rapidly, which his roommate Frank also does.

Charlie's difficulty reading and writing, generally poor communication skills, and poor grasp of grammar and syntax result in constant berating by the rest of the Gang. He is unable to read or write correctly, and keeps a personal journal consisting predominantly of childlike pictures in place of actual sentences. It is quite possible that Charlie has a lifelong case of severe, untreated dyslexia. Mac claims that "no one understands the subtleties of Charlie's retardation better than [Mac]." Like the rest of the Gang, Charlie has a poor grasp of history, current events and geography, sometimes avoiding conversations on these subjects altogether to salvage some dignity. He once described George Washington as "some old dude who looks like Meryl Streep who chopped down a cherry tree like ten million years ago." During the Gang's fight with an Israeli businessman, Charlie incongruously declared they would send their rival "on the first train back to Israel", unaware that Israel is an entire ocean away from Philadelphia.
