General John Hely-Hutchinson, 2nd Earl of Donoughmore, GCB, KC (15 May 1757 – 29 June 1832) was a British Army officer and politician.

In 1801 he was created Baron Hutchinson in the Peerage of the United Kingdom (gaining a seat in the House of Lords) and later succeeded to all his brother Richard's titles.

He spent the next 11 years on half-pay, studying military tactics in France before serving as a volunteer in the Flanders campaigns of 1793 as aide-de-camp to Sir Ralph Abercromby.

In March 1794 he obtained brevet promotion to colonel and the colonelcy of the old 94th Regiment of Foot and then became a major-general in May 1796, serving in Ireland during the Irish Rebellion of 1798, where he was second-in-command at the Battle of Castlebar under General Lake.

In recognition of his "eminent services" during the "late glorious and successful campaign in Egypt", at the request of the King, the United Kingdom Parliament settled on Lord Hutchinson and the next two succeeding heirs male of his body an annuity of £2,000 per annum, paid out of the Consolidated Fund.
