The 218th Brigade was a Home Service formation of the British Army during the First and the Second World Wars.

The 218th Brigade was raised in late 1916 as part of 73rd Division, which had the dual role of training men for overseas drafts and providing forces for home defence.

[7] The Brigade transferred to Yorkshire County Division when that formation was created on 19 March 1941.

The Divisional headquarters became East Riding Coastal Area on 1 December 1941.

The Brigade later transferred to the Durham and North Riding Coastal Area, then to the Northumbrian District before disbanding on 10 November 1942, when its battalions were converted to anti-tank regiments.
