The Ambala Brigade was an infantry brigade of the British Indian Army that formed part of the Indian Army during the First World War. It was formed in November 1914 to replace the original Ambala Brigade that had been mobilized as the 3rd (Ambala) Cavalry Brigade for service on the Western Front. It remained in India throughout the war. The brigade continued to exist between the World Wars and by September 1939 it was designated Ambala Brigade Area. It was broken up in 1941.
