Mr. and Mrs. Brown are unseen characters, like most adults in Peanuts. They are the parents of Charlie Brown and Sally Brown. They are not seen, but in some early strips, the mother has a speech bubble. Like most adults, not much is known about them. They are hardly even mentioned, although, over the years some information has been revealed about them.
Mr. Brown has been referred to as being a barber, like Schulz's father. Mrs. Brown is a housewife. Mrs. Brown is one of the only characters to call Charlie Brown, "Charlie", calling him that on November 7, 1950. However, on later occasions where she talks, she refers to him as "dear" or "sweetie".
