Iolanda Cristina Gigliotti (Italian: [joˈlanda kriˈstiːna dʒiʎˈʎɔtti]; 17 January 1933 – 3 May 1987), professionally known as Dalida (French: [dalida], Italian: [daliˈda]; Arabic: داليدا), was an Italian naturalized French singer and actress. Leading an international career, Dalida has sold over 140 million records worldwide. Her best known songs include "Bambino", "Gondolier", "Les Enfants du Pirée", "Le Temps des fleurs", "Darla dirladada", "J'attendrai", "La Danse de Zorba", "Bang Bang", "Il venait d'avoir 18 ans", "Le Jour où la pluie viendra", "Gigi l'amoroso", "Laissez-moi danser", "Salama ya salama", "Helwa ya baladi", "Mourir sur scène" and "Paroles, paroles" featuring spoken word by Alain Delon.

First an actress, she made her debut in the film A Glass and a Cigarette by Niazi Mustapha in 1955. One year later, having signed with the Barclay record company, Dalida achieved her first success as a singer with "Bambino". Following this, she became the most important seller of records in France between 1957 and 1961. Her music charted in many countries in Europe and Latin America. She collaborated with singers such as Julio Iglesias, Charles Aznavour, Johnny Mathis and Petula Clark.

Although she shot a few films alongside her career as a singer, she effectively reconnected with cinema with The Sixth Day, a film by Youssef Chahine released in 1986. In France, although the film was hailed by critics, it became a commercial failure.

Dalida was deeply disturbed by the suicide of her partner Luigi Tenco in 1967. Despite this, she moved ahead with her career, forming the record label International Show with her brother Orlando, recording more music and performing at concerts and music competitions. After struggling with bouts of depression for many years, Dalida committed suicide by drug overdose on 3 May 1987.
