比莉·霍利戴（英语：Billie Holiday，原名Eleanora Harris，1915年4月7日－1959年7月17日）是美国爵士歌手及作曲家。

绰号"戴夫人" ，霍利戴是一个开创性的爵士乐及流行歌手。影评人John Bush写道，她"永远改变了美国流行歌唱的艺术" 。 她的声乐风格是强烈的灵感乐，开创了一种新的方式操纵的字眼和节奏，也推广了更个性化和亲密的歌唱方式。

她一路上创造了许多专辑，每一张的回应都很热烈，但即使达到人生高峰，仍会被种族歧视，于是再1939年创造了奇异果实〈strange fruit〉，这首歌只在开放咖啡厅演出当天表演，她将所有的灯关掉，并在暗地里怒吼，这首歌也引起社会共鸣，

Eleanora Fagan (April 7, 1915 – July 17, 1959), professionally known as Billie Holiday, was an American jazz musician and singer-songwriter with a career spanning nearly thirty years. Nicknamed "Lady Day" by her friend and music partner Lester Young, Holiday had a seminal influence on jazz music and pop singing. Her vocal style, strongly inspired by jazz instrumentalists, pioneered a new way of manipulating phrasing and tempo. Holiday was known for her vocal delivery and improvisational skills, which made up for her limited range and lack of formal music education. While there were other jazz singers with equal talent, Billie Holiday had a voice that captured the attention of her audience.
