This is a list of aviation-related events from 1944:

The second Schweinfurt raid was a World War II air battle that took place on 14 October 1943, over Nazi Germany between forces of the United States 8th Air Force and German Luftwaffe fighter arm (Jagdwaffe). The American bombers conducted a strategic bombing raid on ball bearing factories to reduce production of these vital parts for all manner of war machines. This was the second attack on the factories at Schweinfurt. American wartime intelligence claimed the first Schweinfurt–Regensburg mission in August had reduced bearing production by 34 percent but had cost many bombers. A planned follow-up raid had to be postponed to rebuild American forces.

Big Week or Operation Argument was a sequence of raids by the United States Army Air Forces and RAF Bomber Command from 20 to 25 February 1944, as part of the European strategic bombing campaign against Nazi Germany. The planners intended to attack the German aircraft industry to lure the Luftwaffe into a decisive battle where the Luftwaffe could be damaged so badly that the Allies would achieve air superiority which would ensure success of the invasion of continental Europe.

Operation Retribution, also known as Operation Punishment, was the April 1941 German bombing of Belgrade, the capital of Yugoslavia, in retaliation for the coup d'état that overthrew the government that had signed the Tripartite Pact. The bombing occurred in the first days of the German-led Axis invasion of Yugoslavia during World War II. The Royal Yugoslav Army Air Force (VVKJ) had only 77 modern fighter aircraft available to defend Belgrade against the hundreds of German fighters and bombers that struck in the first wave early on 6 April. Three days prior, VVKJ Major Vladimir Kren had defected to the Germans, disclosing the locations of multiple military assets and divulging the VVKJ's codes.

Operation Tidal Wave was an air attack by bombers of the United States Army Air Forces (USAAF) based in Libya and Southern Italy on nine oil refineries around Ploiești, Romania on 1 August 1943, during World War II. It was a strategic bombing mission and part of the "oil campaign" to deny petroleum-based fuel to the Axis. The mission resulted in "no curtailment of overall product output."

Prague, the capital and largest city of the German-occupied Protectorate of Bohemia and Moravia, was bombed several times by the Allies during World War II. The first Allied aircraft to fly over Prague was a single bomber of the French Air Force in April 1940, but it dropped propaganda leaflets, not bombs. The first bombing mission was flown by the Royal Air Force (RAF) in October 1941. Prague was then bombed three times by the United States Army Air Forces between the fall of 1944 and spring of 1945. During the Prague uprising of 5–9 May 1945, the Luftwaffe made use of bombers against the rebels.

The Battle of Berlin was a series of attacks on Berlin by RAF Bomber Command along with raids on other German cities to keep German defences dispersed. Air Chief Marshal Sir Arthur Harris, AOC-in-C Bomber Command, believed that "We can wreck Berlin from end to end if the USAAF come in with us. It will cost us between 400 and 500 aircraft. It will cost Germany the war".

The bombing of Stuttgart in World War II was a series of 53 air raids that formed part of the strategic air offensive of the Allies against Germany. The first bombing occurred on August 25, 1940, and resulted in the destruction of 17 buildings. The city was repeatedly attacked over the next four and one-half years by both the RAF and the 8th Air Force as it had significant industrial capacity and several military bases, and was also a center of rail transportation in southwestern Germany. Stuttgart endured 18 large-scale attacks by the Royal Air Force (RAF) during the war, during which 21,016 long tons (21,353 t) of bombs were dropped on the city, but the RAF concluded that its attacks against Stuttgart were not as effective as they could have been: Stuttgart's experience was not as severe as other German cities. Its location, spread out in a series of deep valleys, had consistently frustrated the Pathfinders and the shelters dug into the sides of the surrounding hills had saved many lives.

Jagdgeschwader 3 "Udet" was a Luftwaffe fighter-wing of World War II. The Geschwader operated on all the German fronts in the European Theatre of World War II. It was named after Ernst Udet in 1942.

Allied forces conducted many air raids on Japan during World War II, causing extensive destruction to the country's cities and killing between 241,000 and 900,000 people. During the first years of the Pacific War these attacks were limited to the Doolittle Raid in April 1942 and small-scale raids on military positions in the Kuril Islands from mid-1943. Strategic bombing raids began in June 1944 and continued until the end of the war in August 1945. Allied naval and land-based tactical air units also attacked Japan during 1945.

The capital of Finland, Helsinki was bombed repeatedly during World War II. Between 1939–1944 Finland was subjected to a number of bombing campaigns by the Soviet Union. The largest raids were three raids in February 1944, which have been called The Great Raids Against Helsinki.

Jagdgeschwader 11 was a fighter wing of the German Luftwaffe during World War II. Its primary role was the defense of Northern Germany against Allied day bomber raids. Formed in April 1943 as a split from Jagdgeschwader 1, the unit primarily used the Messerschmitt Bf 109 and Focke-Wulf Fw 190.

The Air Force of the Independent State of Croatia, was the air force of the Independent State of Croatia (NDH), a puppet state established with the support of the Axis Powers on the territory of the Kingdom of Yugoslavia during World War II. The ZNDH was founded under German authority in April 1941, following the German-led Axis invasion of Yugoslavia.

The Aarhus Air Raid took place on 31 October 1944, when 25 Mosquitoes from 140 Wing Royal Air Force (RAF) of the 2nd Tactical Air Force, bombed the Gestapo headquarters at the University of Aarhus. After the Second World War, the RAF called the mission the most successful of its kind during the war.

As the main economic and industrial center in Italy, and the country's second largest city, Milan was subjected to heavy bombing during World War II, being the most bombed city in Northern Italy and one of the most bombed cities in the country.

The bombing of Cagliari was a series of attacks by the United States Army Air Force and the Royal Air Force on the Italian city of Cagliari, the regional capital of Sardinia, during World War II. The raids, aimed at destroying the port facilities and airfields of Cagliari, also resulted in the destruction of most of the city.

Owing to its importance as an industrial center, home to Fiat and several other industries engaged in war production, Turin, the regional capital of Piedmont, suffered over a hundred raids by the Allied air forces during World War II; the Piedmontese capital was thus among the most bombed cities in Northern Italy, suffering damage to about 40% of its housing stock, and over 2,000 victims among its population.

During World War II the Italian city of Bologna, the regional capital and largest city of Emilia-Romagna, suffered nearly a hundred air raids by the Royal Air Force and the USAAF, mostly aimed at disabling its strategically important marshalling yards, used for the movements of German troops and supplies between Northeastern Italy and central Italy. These raids destroyed or damaged almost half of the city, and caused nearly 2,500 victims among its population.
