During World War 2, Operation Epsom (Allies, 1944) was a British attack to seize Caen, France. Three assaults by Canadian and Scottish units of VIII (U.K.) Corps from 26 June to 1 July 1944 achieved local objective but failed to take the city despite heavy casualties. The attack was preceded by a massive artillery bombardment that allowed the attackers to break the German defenses west of the city and begin an envelopment to the south. German counterattacks hit the British on their right, forcing the attackers to give up their attempt just south of Baron.

Operation Epsom was followed by Operation Charnwood.
