Julius Kowalczik (1885-date unknown) was a Austro-Hungarian World War I flying ace credited with five aerial victories.

Though he joined military service as the war began in 1914, he did not transfer to the Austro-Hungarian Aviation Troops until late 1915.

He flew enough missions with this composite squadron in northern Italy that he earned his Field Pilot's Badge.

Although Kowalczik scored no aerial victories, his flying performance brought him a promotion to sergeant and a Silver Medal for Bravery, 2nd Class the following month.

In November, he received the highest award available to an enlisted man, the Gold Medal for Bravery.

[5] On 10 June 1917, Kowalczik joined two other Austro-Hungarian pilots in an attack on an Italian Caproni three-engined bomber.

[5] Kowalczik was so highly thought of that on 20 December 1917, he was deemed fit to be a Offizierstellvertreter (officer candidate).
