153rd Infantry Brigade was a formation of Britain's Territorial Force/Territorial Army that was part of 51st (Highland) Division in both World Wars.

The Volunteer Force of part-time military units formed in Great Britain after an invasion scare in 1859 had no higher organisation than the battalion until the Stanhope Memorandum of December 1888 proposed a comprehensive mobilisation scheme.

The brigade's composition in 1947 was:[6][27] (The Lovat Scouts at Beauly may also have been included,[27] but that regiment was in the process of reforming in the Royal Armoured Corps.
