Sir John Lade, 2nd Baronet (1 August 1759 – 10 February 1838) was a prominent member of Regency society, notable as an owner and breeder of racehorses, as an accomplished driver, associated with Samuel Johnson's circle, and one of George IV's closest friends. While that monarch was still Prince Regent, Lade attracted high society scorn for the extent of his debts and his choice of marriage to low-born beauty Letitia, who was generally supposed to have been the mistress of the executed highwaymanJohn Rann and the Regent's next-youngest brother, the Duke of York.
