Lieutenant-General Sir John Stuart, Count of Maida, GCB (1759 – 2 April 1815) was a British Army officer who served during the French Revolutionary and Napoleonic Wars.

He was present at the siege of Charleston, the battles of Camden and Guilford court-house, and the surrender of Yorktown, returning a regimental lieutenant and an army captain, as was then usual in the Guards.

Stuart, who was in temporary command, realized the weakness of the French position in Calabria and on 1 July 1806 swiftly disembarked all his available forces in the Gulf of Saint Euphemia.

After this success, Stuart marched south and after a series of minor skirmishes, returned to Sicily as he felt his force was too weak to go onto a full offensive against Masséna's foothold in Naples.

Of the events of this time may be mentioned the failure to relieve Colonel Hudson Lowe at Capri, the expedition against Murat's gunboats in the bay of Naples and the second siege of Scylla.
