General Rowland Hill, 1st Viscount Hill, was a British Army officer and English aristocrat who served in the Napoleonic Wars as a brigade, division and corps commander. He became Commander-in-Chief of the British Army in 1828. Well-liked by the soldiers he commanded, he was known as "Daddy Hill".

The Commander-in-Chief of the Forces, later Commander-in-Chief, British Army, or just the Commander-in-Chief (C-in-C), was (intermittently) the professional head of the English Army from 1660 to 1707 and of the British Army from 1707 until 1904. In 1904 the office was replaced with the creation of the Army Council and the appointment of Chief of the General Staff.
