The Tyneside Irish Brigade was a British First World War infantry brigade of Kitchener's Army, raised in 1914. Officially numbered the 103rd (Tyneside Irish) Brigade, it contained four Pals battalions from Newcastle upon Tyne, largely made up of men of Irish extraction. (Another Newcastle brigade — the 102nd (Tyneside Scottish) — contained Tynesiders with Scottish connections).

The brigade's four battalions were known as the 1st to 4th Tyneside Irish. When taken over by the British Army, these became battalions of the Northumberland Fusiliers:

The reserve battalions were the 30th and 34th (Reserve) Battalions, Northumberland Fusiliers (Tyneside Irish).

Along with the 101st and 102nd Brigades, the Tyneside Irish made up the 34th Division which arrived in France in January 1916 and first saw action in the Battle of the Somme that year. On the first day on the Somme, the 34th Division attacked astride the Albert-Bapaume road at La Boisselle. The brigade's task was to follow up the main attack by the 101st and 102nd Brigades and advance on a line from Pozières to Contalmaison.
