Ethel Lilian Voynich, née Boole (11 May 1864 – 27 July 1960) was an Irish-born British novelist and musician, and a supporter of several revolutionary causes. She was born in Cork, but grew up in Lancashire, England. Voynich was a significant figure, not only on the late Victorian literary scene, but also in Russian émigré circles. She is best known for her novel The Gadfly, which became hugely popular in her lifetime, especially in Russia.
