The 25th Infantry Brigade was a war-formed infantry brigade of the British Army that saw active service during both the First and the Second World Wars.
The 25th Brigade was formed in October 1914 just after the outbreak of the First World War with battalions withdrawn from overseas garrisons. It formed part of the 8th Division and served with it on the Western Front until the end of the war, in particular taking part in the Battle of Neuve Chapelle, the Battle of the Somme and the Battle of Passchendaele. It was disbanded in March 1919.
The brigade was reformed in November 1939 just after the outbreak of the Second World War. It saw action during the battles of France and Belgium in May 1940, predominantly with the 50th (Northumbrian) Infantry Division. After being evacuated at Dunkirk, it remained in the United Kingdom with the 47th (London) Infantry Division until it was disbanded at the end of August 1944.
