George Godolphin Osborne, 8th Duke of Leeds (16 July 1802 – 8 August 1872) was a British peer.
He was born the eldest son of Francis Osborne and his wife, The Hon. Elizabeth Eden. In 1832 his father was created Baron Godolphin, upon which George became known as The Hon. George Osborne. When the 1st Baron Godolphin died in 1850, George succeeded his father and became the 2nd Baron Godolphin. Nine years later, George's cousin, the 7th Duke of Leeds, died and he also inherited the dukedom of Leeds, thus becoming styled His Grace The Duke of Leeds. The Godolphin barony and the dukedom remained united until the death of the last duke of Leeds in 1964, when both titles became extinct.
In 1824 he married Harriet Emma Arundel Stewart, an illegitimate daughter of Granville Leveson-Gower, 1st Earl Granville by the Lady Henrietta Frances Spencer, wife of the 3rd Earl of Bessborough. Harriet Stewart was thus a maternal half-sister of the Lady Caroline Lamb.
With Harriet Stewart, he had eight children:
The 8th Duke of Leeds was buried in the Osborne family chapel at All Hallows Church, Harthill, South Yorkshire.
