General Sir John Miller Adye, GCB (1 November 1819 – 26 August 1900) was a British soldier and painter.

Promoted brevet-colonel in 1860, he was specially employed in 1863 in the Northwest frontier of the India campaign, and was Deputy-Adjutant-General, Bengal, from 1863 to 1866, when he returned home.

He was made a KCB in 1873, and was promoted to be major-general and appointed governor of the Royal Military Academy, Woolwich, in 1875, and Surveyor-General of the Ordnance in 1880.

In 1882, he was chief of staff and second in command of the expedition to Egypt, and served throughout the campaign (awarded GCB and thanks of Parliament).

Adye was also a writer and artist, describing his experiences in such works as A Review of the Crimean War (1859), Sitana: a Mountain Campaign on the Borders of Afghanistan in 1863, and Recollections of A Military Life (1895).
