The South Wales Mounted Brigade was a formation of the Territorial Force of the British Army, organised in 1908.

After home defence service, it was posted to Egypt, where it was absorbed into the 4th Dismounted Brigade in March 1916.

It consisted of three yeomanry regiments, a horse artillery battery and ammunition column, a transport and supply column and a field ambulance.

[2] As the name suggests, the units were drawn from the South Wales area, with the exception of the field ambulance which was based in Hereford, England.

[8] The South Wales Mounted Brigade was commanded from 1 January 1913 by Colonel Frederick Fryer.
