8th Army Group Royal Artillery (8 AGRA) was a brigade-sized formation organised by Britain's Royal Artillery (RA) during World War II to command medium and heavy guns. It served in the campaign in North West Europe, participating in the battles in the Orne valley and the bocage south of Caumont before the breakout from the Normandy beachhead, operations to close up to the Maas, and the assault crossing of the Rhine (Operation Plunder).
