Régine Zylberberg (born Régina Zylberberg; 26 December 1929 – 1 May 2022), often known mononymously as Régine, was a Belgian-born French singer, actress, nightclub impresario, and businesswoman. Rising to prominence in the 1950s and 1960s, she built an international nightlife empire with her chain of Régine’s clubs, which became synonymous with celebrity culture, luxury, and the emerging jet set.

Often called the "Queen of the Night," Regine is credited with pioneering the modern discotheque while maintaining a parallel career as a recording artist and entertainer. Rachelle Zylberberg was born in Anderlecht, Belgium, to Polish Jewish parents, Joseph Zylberberg and Tauba Rodstein. She spent much of her early life in hiding from the Nazis in occupied wartime France.
