George Legge, 3rd Earl of Dartmouth (3 October 1755 – 10 November 1810), styled Viscount Lewisham until 1801, was a British politician who sat in the House of Commons from 1778 to 1784.
He was the eldest son of William Legge, 2nd Earl of Dartmouth, and Frances Katherine, daughter of Sir Charles Gounter Nicoll.
[1] At some time during the 1770s he went to Florence as he appears in an important painting by Johann Zoffany which the artist titled the Tribuna of the Uffizi.
He remained out of parliament for the next 17 years, but in 1801 he was summoned to the House of Lords through a writ of acceleration in his father's junior title of Baron Dartmouth.
Lord Dartmouth married Lady Frances (9 February 1761 – 21 November 1838), daughter of Heneage Finch, 3rd Earl of Aylesford, on 24 September 1782.
They had fifteen children: Lord Dartmouth died on 10 November 1810, aged 55, and was succeeded in the earldom by his eldest son, William.
