|Tyneside Scottish Brigade|
|Size||4 New Army battalions|

The Tyneside Scottish Brigade was a British First World War infantry brigade. It was formed from men from the Tyneside area of England and even though it was called a Scottish brigade, they accepted any nationality. The request to the War Office to form the brigade was originally turned down, but after a visit to Newcastle upon Tyne by Lord Haldane on 10 October 1915, permission was granted. The complete Tyneside Scottish Brigade of four battalions was raised by 16 November 1915. Reports of bodies of men and groups of miners marching ten miles into the city to enlist are common.
- 20th Battalion, Northumberland Fusiliers (1st Tyneside Scottish)
- 21st Battalion, Northumberland Fusiliers (2nd Tyneside Scottish)
- 22nd Battalion, Northumberland Fusiliers (3rd Tyneside Scottish)
- 23rd Battalion, Northumberland Fusiliers (4th Tyneside Scottish)
Under the command of Brigadier-General T. P. B. Ternan, the Tyneside Scottish Brigade suffered the worst losses of any brigade on 1 July 1916, the first day of the Battle of the Somme; the Tyneside Irish Brigade had the next worst tally of casualties. The 23rd (4th Tyneside Scottish) Battalion lost 629 men (19 officers and 610 other ranks), the third worst battalion loss of the day. The 20th (1st Tyneside Scottish) Battalion lost 584 men and the 22nd (3rd Tyneside Scottish) Battalion, led by Boer War veteran Lt Col Arthur Elphinstone (a former pupil of Monkton Combe School), lost 537 men. All four battalion commanders were killed (the 21st (2nd Tyneside Scottish) commander had been killed shortly before the battle).
