Baron Suffield, of Suffield in the County of Norfolk, is a hereditary title in the Peerage of Great Britain.

The barony was created in 1786 for Sir Harbord Harbord, 2nd Baronet, who had previously represented Norwich as Member of Parliament in the House of Commons for thirty years (1756–86).

The Harbord baronetcy, of Suffield in the County of Norfolk, had been created in the Baronetage of Great Britain on 22 March 1746 for his father Sir William Harbord, also a former Member of Parliament and who represented what are now termed the "rotten boroughs" of Bere Alston and Dunwich.^[1]

Born William Morden, he assumed the surname of Harbord by Act of Parliament in 1742 in compliance with the Will of his maternal uncle. The first Baron's eldest son and successor as second Baron, served as Lord Lieutenant of Norfolk (1808–21). His younger brother, the third Baron, represented Yarmouth and Shaftesbury as a Whig MP in the House of Commons and after succeeding to the title in 1821, became a Liberal pioneer and leading advocate for the abolition of slavery in the House of Lords.

His younger son, the fifth Baron (who succeeded his half-brother), served in 1886 as Master of the Buckhounds in William Gladstone's third administration, being sworn of the Privy Council the same year, and was appointed KCB (1876) and GCVO (1901). His eldest son, the sixth Baron, was Captain of the Yeomen of the Guard (Deputy Chief Whip in the House of Lords) from 1915 to 1918. On the death of his younger son, the eighth Baron, the line of the fifth Baron expired. The title was inherited by the late Baron's first cousin once removed, who succeeded as the ninth Baron; he was the third son of the Hon. William Harbord, a captain in the British Army, and fourth son of the third Baron. He was succeeded in 1946 by his first cousin as the tenth Baron; he was the son of Reverend the Hon. John Harbord, fifth son of the third Baron. He served as an admiral in the Royal Navy during World War I and was also a Deputy Lieutenant for Norfolk. In 1917 he assumed by Royal Licence the additional surname of Hamond (that of his maternal grandfather, Anthony Hamond). The eleventh Baron served in the British Army during World War II being awarded the Military Cross in 1950, among other decorations. As of 2017^[update] the titles are held by the latter's second son, the thirteenth Baron, who succeeded his brother in 2016.^[2][3]
