The 125th (Lancashire Fusiliers) Brigade was an infantry brigade formation of the British Army that saw active service during both the First and Second World Wars. It was assigned to the 42nd (East Lancashire) Division and served in the Middle East and later in the trenches of the Western Front in the First World War. In the Second World War the brigade, now redesignated 125th Infantry Brigade, fought in Belgium and France before being evacuated at Dunkirk and was then converted into 10th Armoured Brigade.
Throughout its existence the brigade was composed almost entirely of battalions of the Lancashire Fusiliers, except for a few brief months in the early half of the Second World War.
