The following is a character list of main and secondary characters on the Disney Channel series Phineas and Ferb.

Phineas Flynn (voiced by Vincent Martella) Like other characters, he has red hair, his age is not mentioned. Phineas, along with his stepbrother Ferb Fletcher, star in the A-Plot of every episode. The series concerns Phineas's attempts to avoid boredom by finding something new to do every day of the summer vacation. He does this with his less-talkative stepbrother Ferb, and often with many other neighborhood children. He is known to be very selfless and energetic. Phineas has many catch phrases like "Oh, there you are, Perry" or "Hey, Ferb! I know what we're going to do today!" and "Hey, where's Perry?".

Phineas comes from a blended family. The creators chose this arrangement because they considered it underused in children's programming as well as from Marsh's experiences in one. As a character, Phineas has received a positive critical response, with one reviewer describing him and his brother as a "comical pairing." Phineas appears in Phineas and Ferb merchandise, including plush toys,t-shirts, and a video game.

Ferb Fletcher (voiced by Thomas Sangster) is a boy of few words, Phineas's green-haired, intelligent but laconic stepbrother from the United Kingdom and created by Phineas and Ferb co-founders Dan Povenmire and Jeff "Swampy" Marsh. He first appeared in the show's pilot episode, "Rollercoaster."
