Major-General George Johnstone (died 19 December 1825) was a British Army officer. He was commissioned into the infantry 1780, serving in Grenada during Fédon's rebellion in 1795–96. He was afterwards transferred to command a regiment of fencibles in New Brunswick, where he served for a year as acting Lieutenant Governor. In 1810, he was given command of a Highland regiment which served on garrison duty in Cape Colony. Johnstone was promoted to major general in 1814 and given command of the 6th Brigade in the 1815 Waterloo campaign. His brigade was not engaged in the 18 June Battle of Waterloo as they were posted to the extreme right flank, protecting the approaches to Brussels and Ostend. His men fought in the subsequent advance to Paris and helped to storm the fortress of Cambrai on 24 June.
