Earl of Buckinghamshire is a title in the Peerage of Great Britain. It was created in 1746 for John Hobart, 1st Baron Hobart.

The Hobart family descends from Henry Hobart, who served as Attorney General and Lord Chief Justice of the Common Pleas. In 1611 he was created a Baronet, of Intwood in the County of Norfolk, in the Baronetage of England. He was succeeded by his son, the second Baronet. He represented Cambridge, Lostwithiel, Brackley and Norfolk in the House of Commons. He died without surviving male issue and was succeeded by his nephew, the third Baronet. He was the son of Sir Miles Hobart, younger son of the first Baronet. Hobart sat as Member of Parliament for Norfolk. In 1656 he married Mary, daughter of the prominent politician John Hampden.

He was succeeded by his elder son, the fourth Baronet. He was a General of the Horse and was equerry to King William III at the Battle of the Boyne in 1690. He also represented Norfolk, King's Lynn and Bere Alston in Parliament. Hobart was killed in a duel in 1698. His son, the fifth Baronet, served as Treasurer of the Chamber, as Captain of the Honourable Band of Gentlemen Pensioners and as Lord Lieutenant of Norfolk. In 1728 he was raised to the Peerage of Great Britain as Baron Hobart, of Blickling in the County of Norfolk, and in 1746 he was further honoured when he was made Earl of Buckinghamshire, also in the Peerage of Great Britain.
