The 140th (4th London) Brigade was an infantry brigade formation of the British Army's Territorial Army (TA) that had its origins in a South London Brigade (known as the 'Grey Brigade') of the former Volunteer Force. It served on the Western Front in the First World War and was recreated during the Second World War where it served only in the United Kingdom as a training formation.
