Doctor Heinz Doofenshmirtz is the fictional antagonist of the animated television series Phineas and Ferb. Doofenshmirtz is voiced by Dan Povenmire and created by Povenmire and Jeff "Swampy" Marsh. Doofenshmirtz first appeared in the pilot episode of the series and since then has appeared in every episode to date.

A routinely bumbling, incompetent and forgetful mad scientist, Doofenshmirtz is the primary villain of the series and the mastermind behind the B-Plot. Doofenshmirtz's goal in life is to "take over the entire tri-state area" and attempts to do so with obscure contraptions and inventions that tend to have "-inator" as the suffix (as a child, he invented a machine simply called the "Inator). Doofenshmirtz's voice is of Eastern European descent and was a voice Povenmire used since he was a fifteen-year-old having pillow fights with his sister.

In nearly every episode of the series, Doofenshmirtz has an evil scheme or invention that he explains about through the means of a "back story" from his youth. Throughout the series, the back stories explore his mentally abusive and shunned childhood growing up in the fictional village Gimmelshtump, Druelselstein. Doofenshmirtz usually monologues and displays acts of "cartoonish" physical violence towards his nemesis Perry, a skilled anthropomorphic platypus secret agent who disguises himself as the mindless pet of the series main characters.

Doofenshmirtz appears in several merchandise pieces based on the series, particularly the book series and the video game. Doofenshmirtz is portrayed as a bumbling and somewhat incompetent evil genius who hates nearly everything. He is bent on taking over the "entire tri-state area" and uses peculiar contraptions to do so.

Their names tend to end with the suffix "-inator" (exept for Shrinkspheria, an invention he stated "[He] was going to call it a Shrinkinator but I've done the -inator thing before", and are made up of "strange items [he] purchases off the internet" with his large alimony check. Ever since the day they first met, his arch-nemesis has been the secret agent Perry the Platypus. Habitually, Doofenshmirtz's daily encounters with Perry follow a basic chain of events, beginning with Perry being captured, Doofenshmirtz explaining his evil scheme to Perry, Perry escaping from whatever Doofenshmirtz used to trap him, the two waging in combat with each other, with Perry walking away victorious, leading to Doofenshmirtz yelling his catch phrase "Curse you, Perry the Platypus!"
