Jane Stanhope, Countess of Harrington (née Fleming; 23 May 1755 – 3 February 1824), was a society hostess and heiress who served as a lady of the Bedchamber to the British queen Charlotte of Mecklenburg-Strelitz.

At the age of 23, Jane Fleming became engaged to the two years older Charles Stanhope, Viscount Petersham, a war hero who had recently returned from North America to England.

[2] The new Countess of Harrington was soon praised for generosity, as she immediately settled the debts her husband had inherited from her father-in-law and funded the re-purchase of Stable Yard House in St James's.

Surrounded by aristocracy of generally loose morals, she was considered an epitome of virtue, while her younger sister scandalised the society by reportedly having sexual relations with 27 men other than her husband.

"Their sempiternal occupation of tea-drinking" was noted by one of their contemporaries, who found that "neither in Nankin, Pekin, nor Canton was the teapot more assiduously and constantly replenished" than in their home.
