Carmen Delia Dipini (November 18, 1927–August 4, 1998), was a singer of boleros. Born in Naguabo, Puerto Rico, Dipini often entertained her family and friends as a child with her singing. She attended the Eugenio Brac Elementary School where one of the teachers, Mrs. Brenes, realized that Dipini was talented as a singer and encouraged the 7-year-old student to become a singer. In 1941, when she was 14 years old, Dipini went with her parents to San Juan with the intention of participating in a radio talent show. As a result she would make her radio singing debut on the radio program of Rafael Quiñones Vidal.

In 1948, Dipini, who had befriended fellow Puerto Rican singer Ruth Fernández, left for New York City at her friend's recommendation. While in New York, she participated and won the first place prize in a talent show held at the Triboro Theater. Part of the prize was a singing contract with Johnny Albino and The San Juan Trio and she would go on to record her first "hit" "El Día que nací yo" (The Day I was Born) with the trio.
