The 164th (North Lancashire) Brigade was an infantry brigade of the British Army that saw active service in World War I and remained in the United Kingdom throughout World War II, now as the 164th Infantry Brigade. Throughout both wars the brigade was part of the 55th (West Lancashire) Division.

The brigade was raised in 1908 when the Territorial Force was created and was originally formed as the North Lancashire Brigade, attached to the West Lancashire Division. The brigade was composed of two Volunteer battalions of the King's Own Royal Regiment (Lancaster) and two of the Loyal Regiment (North Lancashire).

The division was mobilised on 5 August 1914, the day after Britain declared war on Germany, thus beginning the Great War.

From late 1914 to early 1915 units of the brigade began to be sent independently overseas, mainly to France and Belgium, and were replaced by the 2nd Line units being formed, the 170th (2/1st North Lancashire) Brigade of 57th (2nd West Lancashire) Division. To differentiate the 1st Line battalions from the 2nd Line, the prefix '1/' was adopted by all 1st Line battalions (1/4th King's Own) and '2/' for all 2nd Line.

In April 1915 the 164th Brigade was redesignated 154th Brigade and joined the 51st (Highland) Division. In June 1916 the brigade, now again redesignated 164th (1st North Lancashire) Brigade, returned to the West Lancashire Division, now the 55th (West Lancashire) Division, and served with it for the rest of the war on the Western Front in battles at Passchendaele, Cambrai and Estaires in 1918.
