Sharon Gamboa Cuneta was born on January 6, 1966, at Our Lady of Lourdes Hospital in Santa Mesa, Manila. Her mother, Elaine (née Gamboa; 1934–2014), who had one-quarter American blood, was the sister of actress Helen Gamboa. Her father, Pablo Cuneta (1910–2000), was a former mayor of Pasay. She has a brother named Cesar "Chet" who ran for Pasay mayor in the 2019 elections but lost.

Cuneta grew up listening to her father's record collection. Her mother, Elaine Gamboa, was a piano major at the University of Santo Tomas Conservatory of Music in her youth. The young Cuneta would take up piano, guitar, and flute lessons to broaden her musical training and exposure at a young age. At the age of three, Cuneta would accompany her aunt, actress Helen Gamboa, during recordings of her television shows.

Another of her first proper TV appearances was on Ike Lozada's show, for the "Bulilit" portion, where she mimicked the songs of her aunt, Helen Gamboa. Cuneta was just as young when she appeared in her first movie, the Rosanna Ortiz-George Estregan vehicle Lovers for Hire where she played one of Roderick Paulate's playmates.

Cuneta attended St. Paul College, Pasig, and International School Manila for her primary to secondary education.

In January 1978, the 12-year old Cuneta made her first visit to 782 Aurora Boulevard, which was the address of Vicor Records. Her Uncle and Vice-President of Vicor, Tito Sotto, asked her to record "Tawag Ng Pag-Ibig" which he produced for her at Vicor and shortly after, she was on television promoting her own song for the first time and on the TV show Discorama hosted by TVJ.
