The Battle of Greece (also known as Operation Marita, German: Unternehmen Marita) is the common name for the invasion of Allied Greece by Nazi Germany in April 1941 during World War II. Concomitant to the stalled Greco-Italian War, it is usually distinguished from the Battle of Crete, which came after mainland Greece had been subdued. These Axis operations were part of the greater Balkan Campaign of Germany.

At the time of the German invasion, Greece was at war with Fascist Italy, following the Italian invasion on 28 October 1940. The Greeks joined the Allies and defeated the initial Italian attack and the counter-attack of March 1941. When Operation Marita began on 6 April, the bulk of the Greek Army was on the Greek border with Albania, then a protectorate of Italy, from which the Italian troops had attacked. German troops invaded from Bulgaria, creating a second front. Greece had already received a small, inadequate reinforcement from British Empire forces in anticipation of the German attack, but no more help was sent afterward. The Greek army found itself outnumbered in its effort to defend against both Italian and German troops. As a result, the Metaxas defensive line did not receive adequate troop reinforcements and was quickly overrun by the Germans, who then outflanked the Greek forces at the Albanian border, forcing their surrender. The British Empire forces were overwhelmed and forced to retreat, with the ultimate goal of evacuation. For several days, Allied troops played an important part in containing the German advance on the Thermopylae position, allowing ships to be prepared to evacuate the units defending Greece. The German Army reached the capital, Athens, on 27 April and Greece's southern shore on 30 April, capturing 7,000 British Empire forces and ending the battle with a decisive victory. The conquest of Greece was completed with the capture of Crete a month later. Following its fall, Greece was occupied by the military forces of Germany, Italy and Bulgaria.
