Frieda is a character in the comic strip Peanuts by Charles Schulz. She made her debut on March 6, 1961, when Linus introduced her to Charlie Brown. She sat behind Linus in school, and although he considered her a friend, he also confessed that she was such a chatterbox, he hadn't heard a word their teacher said the whole semester. Her most prominent feature is her "naturally curly hair," which she manages to work into every conversation, to the dismay of those around her. She eventually joined Charlie Brown's baseball team as an outfielder, though she tends to be more interested in talking to fellow outfielder Lucy than she is in the game.

Frieda often harasses Snoopy into chasing rabbits, which he is always reluctant to do. Once out of Frieda's sight he frolics and plays with the rabbits instead. Once, in a fit of frustration, she reported Snoopy's behavior to the "Head Beagle," which led to him being found guilty of not meeting his rabbit quota and left the neighborhood kids mad at her for turning him in. Snoopy's dislike of Frieda is compounded by her owning a cat named Faron, whom she frequently carries around in her arms.

Frieda was a regularly featured character throughout the 1960s, but as more new characters were phased in towards the end of the decade she began appearing less often. Her last official appearance in the strip was on March 20, 1975, just over 14 years after her introduction, although unnamed girls who resemble her would occasionally pop up in later years.
