The 2nd Infantry Division was a Regular Army infantry division of the British Army, with a long history. Its existence as a permanently embodied formation dated from 1809, when it was established by Lieutenant General Sir Arthur Wellesley (later to become the Duke of Wellington), as part of the Anglo-Portuguese Army, for service in the Peninsular War. (Prior to this, it was common for formations with the same number to be temporarily established for a single campaign and disbanded immediately afterwards; divisions remained a permanent part of the British Army's structure only after the Napoleonic Wars).

The division was associated with the north of England. The divisional insignia, the Crossed Keys of Saint Peter, were originally part of the coat of arms of the Diocese of York, and were adopted before or during the First World War. It was disbanded on 1 April 2012.

The first commander of the 2nd Division was Major General Rowland Hill. Under his command, the division took part in the Second Battle of Porto and the battles of Talavera and Bussaco.

In 1811, Major General the Hon. William Stewart became commander of the division. Stewart was apparently a magnificent Lieutenant Colonel, but a disastrous General. The division suffered heavy casualties at the Battle of Albuera. For the rest of 1812, the division was part of a detachment (essentially a corps) under Rowland Hill which covered the southern flank of Wellington's main army. It thus acquired the nickname of the "Observing Division", but was also known as the "Surprisers", after taking the French by surprise in engagements at Arroyo Molinos and Almaraz.
