Jane Elizabeth Digby (3 April 1807 – 11 August 1881) was an English aristocrat, famed for her remarkable love life and lifestyle.

She died in Damascus, then part of the Ottoman Empire, as the wife of Arab sheikh Medjuel el Mezrab, who was 20 years her junior.

Jane's father seized the Spanish treasure ship Santa Brígida in the action of 16 October 1799 and his share of the prize money established the family fortune.

After successive affairs with her maternal cousin Colonel George Anson and Prince Felix of Schwarzenberg, she was divorced from Lord Ellenborough in 1830 by an act of Parliament.

Though she was not legally divorced from Venningen until 1842, Digby converted to the Greek Orthodox faith and married Theotokis in Marseille, France, in 1841.

The couple moved to Greece with their son Leonidas (21 March 1840 Paris, France – 1846 Bagni di Lucca, Italy).

It has been written that Jane Digby was referred to as Shaikhah Umm al-Laban (literally sheikha mother of milk) due to the colour of her skin.

Half of each year was spent in the nomadic style, living in goat-hair tents in the desert, while the rest was enjoyed in a palatial villa that she had built in Damascus.
