If you are asking who is chipmunks brother, the quick answer is simple: the Chipmunks are brothers named Alvin, Simon, and Theodore.
They are the three Seville brothers at the heart of the franchise. That sibling setup gives the whole story its energy, humor, and heart.
The brothers are Alvin, Simon, and Theodore. Alvin is usually the most noticeable one.
Simon is the brains of the group, and Theodore is the youngest and sweetest. That three-part dynamic helps the characters work so well together, whether you know them from cartoons, films, or music.
The Quick Answer: The Brothers Are Alvin, Simon, And Theodore
Those are the names you are looking for. They are the core of the Chipmunks story.
Each one has a clear personality that makes the trio easy to tell apart.
Alvin Seville As The Most Recognizable Brother
Alvin wears a red sweater and leads the group. You usually notice him first.
He is bold, energetic, and often causes the group’s trouble. He became the face of Alvin and the Chipmunks.
Justin Long voices Alvin in the live-action films. That version keeps his fast-talking personality front and center.
Simon Seville As The Smart Middle Brother
Simon, the logical middle brother, usually thinks through the plan before anyone else. He balances Alvin’s chaos with patience and reason.
Matthew Gray Gubler voices Simon in the films. His calm, precise style matches the character well.
Theodore Seville As The Sweet Youngest Brother
Theodore is the youngest brother. He is gentle, trusting, and affectionate.
His softer personality helps round out the trio. Jesse McCartney voices Theodore in the films, which fits his warm, innocent tone.
How Dave Seville Fits Into The Family
Dave Seville is part of the family setup, but he is not one of the chipmunk brothers. He acts as the human adult in the household and helps the trio stay grounded.
David Seville As Guardian Rather Than Brother
David Seville, also called Dave Seville, serves as the chipmunks’ guardian and manager. In many versions, he is the steady adult who keeps Alvin in line while supporting Simon and Theodore.
Jason Lee plays Dave in the live-action films. His role as caretaker is especially clear.
Why People Confuse Dave With The Main Cast
People often mention Dave because he is always close to the brothers and usually involved in their biggest problems. When Alvin gets into trouble, Dave reacts to it, which makes him feel central to the story.
You may also hear his name linked to David Seville and the Chipmunks, since the setup connects the human guardian with the trio so closely.

Brittany, Jeanette, And Eleanor As The Sister Trio
The Chipettes are Brittany, Jeanette, and Eleanor. They are sisters rather than brothers.
