Juliet Anderson (born Judith Carr), also known as Aunt Peg, (July 23, 1938 – January 11, 2010) was an American pornographic actress and adult movie producer, relationship counselor and author. Entering the adult movie business relatively late in life (at age 39), she quickly built a reputation as one of the premier performers in the so-called "Golden Age of Porn", appearing in over seventy films—often as "Aunt Peg", a role portrayed as a giddy, insatiable woman determined to enjoy life and sex to the maximum extent possible. In 1987, she started a new career as a relationship counselor and massage therapist, before returning to adult entertainment in the mid-1990s.

Judith Carr was born and grew up in Burbank, California, the daughter of a jazz trumpet player and an aspiring nurse. She was afflicted with both childhood arthritis and Crohn's disease and spent a sizable portion of her youth in the hospital or on bedrest. Graduating from Burbank High School in 1956 (where she was a straight-A student), she briefly attended Long Beach State College as an art major before relocating to Hayama, Japan, in 1961, with her then lover, a Navy sailor. A brief marriage to him did not work out, ending in 1964, and she spent the next thirteen years in various occupations, including clerical worker, teaching assistant in kindergarten and high school, and English as a Second Language teacher, and working as a radio journalist in Finland.

In 1963, while living in Miami, she was secretary to a producer of "nudie" movies and a receptionist at the Burger King home office; she also worked for Avis during this period. In her website autobiography, she indicates that she appeared in an (unnamed) sexploitation film in 1963, portraying a police sergeant.

During this time, she was known by her birth name of Judith Carr. She did not begin using the moniker "Juliet Anderson" until later in her adult film career, when she made the transition from 8mm productions to feature films. She has also used the stage names of Alice Rigby, Judy Callin, Ruby Sapphire, Judy Carr, Aunt Peg, Judy Fallbrook, and Judith Anderson.
