Gloria Estefan is a Cuban-American singer, actress, and businesswoman. Estefan is an eight-time Grammy Award winner, a Presidential Medal of Freedom recipient, and has been named one of the Top 100 greatest artists of all time by both VH1 and Billboard.[2] Estefan's record sales exceed 100 million worldwide, making her one of the best-selling female singers of all time.

A contralto, Estefan started her career as lead singer of Miami Latin Boys, which was later renamed Miami Sound Machine. She and Miami Sound Machine earned worldwide success with their 1985 single "Conga", which became Estefan's signature song. The group followed this with a number of hit singles throughout the decade, including "Anything for You", "1-2-3", "Bad Boy", and "Rhythm Is Gonna Get You". The group was redubbed as Gloria Estefan and Miami Sound Machine with the release of their 1987 album Let It Loose, and in 1989, Estefan rose to solo stardom with her debut solo album Cuts Both Ways.

In March 1990, Estefan sustained a life-threatening cervical fracture of her spine when her tour bus was involved in a crash near Scranton, Pennsylvania. She underwent an emergency surgery, but made a full recovery. The following year, Estefan launched her comeback with a worldwide tour and album, Into the Light. Estefan's 1993 Spanish-language album, Mi Tierra, won the first of her three Grammy Awards for Best Tropical Latin Album. The album was also the first Diamond album in Spain. Estefan's catalog of international solo hits includes "Don't Wanna Lose You", "Get On Your Feet", "Coming Out of the Dark", "Turn the Beat Around", "You'll Be Mine (Party Time)", and "Heaven's What I Feel".

Gloria Estefan was born Gloria María Milagrosa Fajardo García in Havana, Cuba on September 1, 1957 to parents José Fajardo (1933–1980) and Gloria García (1930–2017). Estefan's maternal grandparents were Spanish immigrants. Her maternal grandfather, Leonardo García, emigrated to Cuba from Pola de Siero, Asturias, Spain, where he married Gloria's grandmother, Consuelo Pérez, who was originally from Logroño, Spain. Consuelo's father Pantaleón Pérez served as the head chef to two Cuban presidents. Estefan's paternal side also had musical sensibilities, as the lineage had a famous flautist and a classical pianist.

Estefan's mother Gloria Fajardo, nicknamed "Big Gloria", won an international contest during her childhood and received a Hollywood offer to dub Shirley Temple's films in Spanish. However, Leonardo García did not permit his daughter to pursue the offer. Gloria Fajardo earned a Ph.D. in education in Cuba, but her diploma and other papers were destroyed by Cuban officials when she left for the United States.

Estefan's paternal grandparents were José Manuel Fajardo González and Amelia Montano. José Manuel was a Cuban soldier and a motor escort for the wife of Cuban president Fulgencio Batista, and Amelia Montano was a poet. As a result of the Cuban Revolution, the Fajardo family fled and settled in Miami, in 1959, and ran one of the first Cuban restaurants in the city. In 1961, Estefan's father José participated in the failed Bay of Pigs Invasion. He was captured by his cousin, who was a member of Fidel Castro's army, and imprisoned in Cuba for nearly two years. On his return, he joined the United States military and fought in the Vietnam War.

After returning from the Vietnam War in 1968, Estefan's father became ill with multiple sclerosis, attributed to Agent Orange exposure that he suffered in Vietnam.  Estefan helped her mother care for him and her younger sister Rebecca, nicknamed "Becky" (b. 1963), while her mother worked to support them. Gloria Fajardo first had to regain her teaching credentials, then worked as a schoolteacher for the Dade County Public School system. When Estefan was nine, she alleged that a music teacher hired to teach her guitar lessons sexually abused her. She alleged that the man told her that he would kill her mother if she told anyone about the abuse. Estefan told her mother who alerted the police of the allegation; charges were not pressed because of the additional trauma she felt Estefan would undergo as a result of testifying against the perpetrator. When Estefan was 16, her father's illness led him to be hospitalized at a Veterans Administration medical facility.
