Operation Jupiter was an offensive by VIII Corps of the British Second Army from 10 to 11 July 1944. The operation took place during the Battle of Normandy in the Second World War. The objective of the 43rd (Wessex) Infantry Division was to capture the villages of Baron-sur-Odon, Fontaine-Étoupefour, Château de Fontaine-Étoupefour and to recapture Hill 112. An attached brigade of the 15th (Scottish) Infantry Division would take Éterville, Maltot and the ground up to the River Orne and then the tanks of the 4th Armoured Brigade, supported by infantry, would advance through the captured ground and secure several villages to the west of the River Orne. It was hoped that the initial objectives could be captured by 9:00 a.m., after which the 4th Armoured Brigade would exploit the success.

VIII Corps was a British Army corps formation that existed during the First and Second World Wars. In the latter, it took part in the Normandy Campaign in 1944, where it was involved in Operation Epsom and Operation Goodwood. It would later play a supporting role in Operation Market Garden and finish the war by advancing from the Rhine to the Baltic Sea.
