Lieutenant-General Robert Ballard Long (4 April 1771 – 2 March 1825) was an officer of the British and Hanoverian Armies who despite extensive service during the French Revolutionary and Napoleonic Wars never managed to achieve high command due to his abrasive manner with his superiors and his alleged tactical ineptitude.
 Although he remained a cavalry commander in the Peninsular War between 1811 and 1813, the British commander Wellington became disillusioned with Long's abilities.
 Wellington's opinion was never expressed directly, though when the Prince Regent manoeuvred his favourite, Colquhoun Grant into replacing Long as a cavalry brigade commander, Wellington conspicuously made no effort to retain Long.
 Other senior officers, including Sir William Beresford and the Duke of Cumberland, expressed their dissatisfaction with Long's abilities.
 The celebrated historian, and Peninsula veteran, Sir William Napier was a severe critic of Beresford's record as army commander during the Albuera Campaign; in criticising Beresford he involved Long's opinions as part of his argument.
 The publication of Napier's history led to a long running and acrimonious argument in print between Beresford and his partisans on one side, with Napier and Long's nephew Charles Edward Long (Long having died before the controversy reached the public arena) on the other.
 Recently Long's performance as a cavalry general has received more favourable comment in Ian Fletcher's revisionist account of the British cavalry in the Napoleonic period.
