John Alves Arbuthnot of Coworth House (7 October 1802 – 29 August 1875) was a British banker, co-founder of Arbuthnot Latham, a private bank.
Arbuthnot was born on 7 October 1802 at Queen Street in Edinburgh, Scotland into Clan Arbuthnott. He was the second son of Sir William Arbuthnot, 1st Baronet (1766–1829) and Anne Alves (d. 1846). His elder brother was Sir Robert Keith Arbuthnot, 2nd Baronet. Among his younger siblings were George Clerk Arbuthnot (father of Charles Ramsay Arbuthnot), Archibald Francis Arbuthnot (who married Hon. Gertrude Sophia Gough, daughter of the 1st Viscount Gough, father of Maj.-Gen. William Arbuthnot and Sir George Gough Arbuthnot), William Urquhart Arbuthnot (a member of the Council of India) and James Edward Arbuthnot. His father served as Lord Provost of Edinburgh and Lord Lieutenant of the City of Edinburgh.[1]

On 13 May 1833, Arbuthnot and Alfred Latham co-founded Arbuthnot Latham at 33 Great St Helen's, Lime Street (near The Gherkin) in the City of London. Originally starting as a general merchant business, it soon began involving itself in finance and lending operations.[3] [4] He also served as a director of the London Assurance Company and of the London and Colonial Bank.
