Lieutenant Colonel George Rowland Stanley Baring, 3rd Earl of Cromer (28 July 1918 – 16 March 1991), styled Viscount Errington before 1953, was a British banker and diplomat.

A member of the Baring family and the eldest son of the 2nd Earl of Cromer and his wife Ruby Elliot-Murray-Kynynmound, he was educated at Eton and Trinity College, Cambridge, where he left after a year.

He served with the Grenadier Guards during the Second World War, where he gained the rank of Lieutenant-Colonel and became a Member of the Order of the British Empire.

During his governorship he clashed with the incoming Labour Prime Minister Harold Wilson over Cromer's desire to see government spending contained, which may have contributed to his decision not to seek a second term.

Esmé Harmsworth was a Lady of the Bedchamber to Queen Elizabeth II, while Lavinia Baring was a Lady-in-Waiting to Diana, Princess of Wales.
