The London Mounted Brigade (later numbered as the 8th Mounted Brigade) was a yeomanry brigade of the British Army, formed as part of the Territorial Force in 1908. It served dismounted in the Gallipoli Campaign before being remounted to serve in the Salonika and Sinai and Palestine Campaigns in World War I. In April 1918, it was merged with elements of the 8th (Lucknow) Cavalry Brigade to form 11th Cavalry Brigade. It remained in Palestine after the end of the war on occupation duties.
