Sackville George Stopford-Sackville DL, JP (19 March 1840 – 6 October 1926), known as Sackville Stopford until 1870, was a British Conservative politician.
Born Sackville Stopford, Stopford-Sackville was the eldest son of William Stopford-Sackville, son of Reverend the Hon. Richard Bruce Stopford, younger son of James Stopford, 2nd Earl of Courtown. His mother was Caroline Harriett, daughter and heiress of the Hon. George Sackville, younger son of George Germain, 1st Viscount Sackville.

He was educated at Christ Church, Oxford.
Stopford-Sackville was returned to Parliament for Northamptonshire North in 1867, a seat he held until 1880. He remained out of the House of Commons for the next twenty years trying unsuccessfully to return to parliament in the 1894 Wisbech by-election. In 1900 he was re-elected for his previous constituency Northamptonshire North, and continued to represent it until 1906. He was also an Alderman of the Northamptonshire County Council and served as a Deputy Lieutenant and Justice of the Peace of that county.
Stopford-Sackville married Edith Frances, daughter of William Rashleigh, in 1875. There were no children from the marriage. She died in December 1905. Sackville-Stopford survived her by over twenty years and died on 6 October 1926, aged 86.
