The 136th (2/1st Devon & Cornwall) Brigade was a formation of the British Army during the First World War. It was assigned to the 45th (2nd Wessex) Division, a second line Territorial Force formation. It did not see any service against the Central Powers during the war, as it was sent to British India, replacing units of the regular army, which were then able to take part in the fighting. As the war progressed, most of the brigade's battalions saw active service as part of other brigades.
