The 148th Infantry Brigade was an infantry brigade formation of the British Army that served in both World War I and briefly in World War II as part of the 49th (West Riding) Infantry Division and disbanded after the war.

The brigade was raised in 1908 upon the creation of the Territorial Force, which was formed by the amalgamation of the Yeomanry and the Volunteer Force. The 3rd West Riding Brigade was assigned to the West Riding Division. The brigade consisted of two volunteer battalions of the King's Own (Yorkshire Light Infantry) and two of the York and Lancaster Regiment.

The division was mobilised shortly after the outbreak of war and started training. In 1915 the division became the 49th (West Riding) Infantry Division and the brigade was numbered 148th (1/3rd West Riding) Brigade. The battalions adopted the '1/' prefix (for example, 1/4th KOYLI) to differentiate them from their 2nd Line units being formed. The 2nd Line consisted of the few men who did not volunteer to serve overseas and was intended to act as home service and as a reserve for the 1st Line. The 2nd Line units were 187th (2/3rd West Riding) Brigade, 62nd (2nd West Riding) Division. With the 49th Division, the 148th Brigade saw service on the Western Front during the First World War from 1915 to 1918.

Due to a shortage of manpower in the British Expeditionary Force (BEF) it was decided to reduce all British divisions serving on the Western Front from twelve to nine infantry battalions, all brigades reducing from four to three, and so the 1/5th KOYLI was transferred from 148th Brigade to the 187th (2/3rd) West Riding Brigade of 62nd (2nd West Riding) Division where they amalgamated with the 2/5th KOYLI and were renamed the 5th Battalion.
