The 9th Jat Regiment was an infantry regiment of the British Indian Army

It was formed in 1922. The 9th Jats were first raised by the East India Company in 1803 as the 22nd Bengal Regiment of Native Infantry. The unit was immediately plunged into the Mahratta wars, before embarking on the first Afghan War, the Sikh Wars and the Burma wars. During the Indian Mutiny, the regiment remained relatively inactive, although their British officers took part in the mutiny's suppression. Between the mutiny and WWI, the unit was involved in fresh fighting in Burma, Assam, Somaliland and the Boxer Rising in China. The regiment went to France on the outbreak of war in 1914, but their sojourn in the trenches was brief, and they were soon in Egypt training for the war in Mesopotamia (Iraq). After the war, the regiment took part in the third Afghan war and the tribal fighting in Waziristan. The Regiment saw a great deal of fighting with the Jats showing their mettle in North Africa, Ethiopia, Burma, Malaya, Singapore, and Java-Sumatra.

A large number of gallantry awards were won including a Victoria Cross (by Jemadar Abdul Hafiz) and two George Crosses (by Islam-ud-Din and Abdul Rahman). At the end of the war the Regiment, in company with other regiments of the Indian Infantry, dropped the numeral 9 from its title and became simply the Jat Regiment.
