The Prince of Wales's Division was a British Army command, training and administrative apparatus designated for all land force units in the West of England and Wales.

The depot was established at Whittington Barracks in Staffordshire.

[5] Under the Army 2020 reorganisation, the 3rd Battalion, Mercian Regiment (Staffords) and the 2nd Battalion, Royal Welsh (Royal Regiment of Wales) will both be disbanded, while the Royal Irish Regiment (27th (Inniskilling), 83rd, 87th and Ulster Defence Regiment) will be transferred to the administration of the Prince of Wales' Division.

This saw the Mercian Regiment being moved to the King's Division, with the Royal Regiment of Scotland (which encompassed the entirety of the Scottish Division) transferred to a single administrative formation with the Royal Welsh and the Royal Irish Regiment.

This new administrative formation became known as the Scottish, Welsh and Irish Division.
