Jenny Hill (1848 – 28 June 1896), born Elizabeth Jane Thompson, was an English music hall performer of the Victorian era known as "The Vital Spark" and "the Queen of the Halls". Her repertoire of songs included "'Arry", "The Boy I Love is Up in the Gallery", "The Little Vagabond Boy", "I've Been a Good Woman to You" and "If I Only Bossed the Show".
Hill made her stage début at an early age in a pantomime version of Mother Goose at the Aquarium Theatre in Westminster. After a difficult apprenticeship at a public house, she embarked on a career in music hall by 1868. She made a success at the London Pavilion, and until 1890 she was at the peak of her fame, enjoying top-billing at music halls across London and in the northern provinces. In 1879 she became the proprietor of her first music hall and later owned or operated several more, but without success.
By 1889 her health was declining, and she was forced to cancel a number of theatrical engagements. After a tour of New York in 1891, she returned to London where she made some appearances until 1894, but was mostly in poor health.
