Sybil Carlisle (10 February 1871 – 1951) was a British actress born in South Africa who was active in both England and the United States during the 19th and 20th centuries.

[3] After playing the main part of Persis Harrison in Gudgeons in 1893 at Terry's Theatre, she was offered training by the playwright Augustin Daly, which lasted for two years.

[7][10] These included The School for Scandal, Lucetta in The Two Gentlemen of Verona, Oberon in A Midsummer Night's Dream, and Love on Crutches.

[7] As a result of her successful performances in the United States, Carlisle earned the description of "The Maude Adams of England".

[11] Carlisle's subsequent theatrical appearances included Madame Polenta in Betsy, and Poppy Jannaway in My Friend the Prince.

[13][15] It is possible that Galsworthy's romantic feelings towards Carlisle resulted in his detachment from his career in law and prompted his father to send him abroad.
