The 31st Armoured Brigade was an armoured brigade formation of the British Army, created during World War II.

The unit was formed in the UK on 15 January 1941 as the 31st Army Tank Brigade, in Northern Command, and initially comprised the 9th and 10th Royal Tank Regiments. The 141st Regiment Royal Armoured Corps was added on 8 November 1941, and on 29 November it was transferred to South Eastern Command.

In May 1942 the unit was redesignated the 31st Tank Brigade, and was transferred to the 53rd (Welsh) Infantry Division, as part as an experimental "mixed" formation of a tank and two infantry brigades. However, the experiment was abandoned on 10 September 1943, as judged unsuitable for the terrain in north-western Europe. During this time, on 1 April 1943, the 10th RTR was renamed 7th Royal Tank Regiment, after the original unit of that name that was destroyed at the Battle of Gazala in May–June 1942.

31st Tank Brigade first saw action as a follow-up unit in the Normandy landings, arriving in northern France on 19 June 1944, equipped with Churchill tanks, and supporting 15th (Scottish) Infantry Division until the end of July in operations to capture the town of Caen.

141st Regiment RAC had been detached from the brigade on 21 June, to re-equip with the Churchill Crocodile flame-throwing tank, and it was also decided to convert the entire brigade to the "Crocodile". 7th RTR was detached from the brigade on 17 August 1944, and was briefly replaced by 144th Regiment Royal Armoured Corps on the 23rd. Both the 144th RAC and 9 RTR were detached on 31 August, and on 4 September the brigade was transferred to the 79th Armoured Division, where it was rejoined by 141st Regiment RAC, and was brought back up to strength with the addition of 11th Royal Tank Regiment and the 1st Battalion, Fife and Forfar Yeomanry on 2 November. 11th RTR was detached on 22 December, and replaced by the 49th Armoured Personnel Carrier Regiment and the 1st Canadian Armoured Personnel Carrier Regiment, both equipped with the "Kangaroo", an obsolete tank with its gun turret removed, converted into a primitive armoured personnel carrier.
