Lieutenant-General John Keane, 1st Baron Keane was an Irish soldier, whose military exploits in the First Anglo-Afghan War led to him being created Baron Keane of Ghuznee.

The First Anglo-Afghan War was fought between the British Empire and the Emirate of Kabul from 1838 to 1842. The British initially successfully invaded the country taking sides in a succession dispute between emir Dost Mohammad Khan (Barakzai) and former King Shah Shujah (Durrani), whom they reinstalled upon occupying Kabul in August 1839. The main British Indian force occupied Kabul and endured harsh winters. The force and its camp followers were almost completely massacred during the 1842 retreat from Kabul.
