Ernst von Steinberg (26 September 1692 – 3 October 1759) was a Hanoverian minister and head of the German Chancery in London from 1737 until 1748.
He gained his position due to the influence of his cousin, Amalie von Wallmoden, the future Countess of Yarmouth, who was the mistress of George II.
He was politically conservative and rarely expressed his opinion to King George, acting instead as primarily a secretary.
His successor, Philipp Adolph von Münchhausen, would follow in his footsteps.
He and his wife had a son, George August (born 18 May 1739),[1] and a daughter, Eva.
