Janette Mary Fernie Ranken (married name Thesiger) (16 December 1877 – 21 May 1970) was an English actress who worked under the name of Juliet Hardinge.

She was the wife of actor Ernest Thesiger and sister of the painter William Bruce Ellis Ranken.

She left Jourdain and on 30 May 1917 Janette Ranken married Ernest Thesiger.

[1][2] Hilary Spurling, biographer of Ivy Compton-Burnett, who was friend of Ernest Thesiger through Jourdain, suggests that Thesiger and Janette wed largely out of their mutual adoration of William, who shaved his head when he learned of the engagement.

At her brother's death in 1941, Janette Ranken gifted over 200 works to be distributed amongst English public galleries and museums.
