The 134th Infantry Brigade was an infantry brigade of the Territorial Force, part of the British Army. It was formed in the First World War as a duplicate of the Hampshire Brigade and was originally formed as the 2nd/1st Hampshire Brigade in 1914–1915 before later being renamed as the 134th (2/1st Hampshire) Brigade. It was sent overseas to India in December 1914 to relieve Regular Army units for service in France. The brigade remained there for the rest of the war, supplying drafts of replacements to the British units fighting in the Middle East and later complete battalions. By September 1917 the last of its battalions had departed.
