The Junkers Ju 89 was a heavy bomber aircraft designed for the Luftwaffe prior to World War II. Two prototypes were constructed, but the project was abandoned without the aircraft entering production. Elements of its design were incorporated into later Junkers aircraft.

From the very beginnings of the Luftwaffe in 1933, General Walther Wever, the chief of staff, realised the importance that strategic bombing would play in any future conflict. He began secret talks with two of Germany's leading aircraft manufacturers, Dornier and Junkers, requesting designs for a long-range bomber. The two companies responded with the Dornier Do 19 and the Junkers Ju 89 respectively, and the RLM (Reichsluftfahrtministerium, "Reich Aviation Ministry") ordered prototypes for both aircraft in 1935.

The Ju 89 and its competitor both proved promising, but fell victim to a change of direction within the Luftwaffe. Wever was killed in a plane crash in 1936 and his successor, Albert Kesselring did not see the value in such aircraft, emphasising instead the need for tactical bombers to act in an army support role. While Kesselring's beliefs seemed validated by Germany's early successes in the Blitzkrieg, the lack of strategic bombing capability severely hampered the Luftwaffe in the Battle of Britain. While the Allied air forces went on to prove Wever right about the importance of this role in air warfare, Germany never had a chance to catch up.

The first prototype of the Ju 89 flew on April 11 1937, and the RLM cancelled the strategic bomber requirement just two and a half weeks later, on April 29. Junkers completed a second prototype in July, and continued flight tests to learn more about the flight control of large aircraft. During these tests, the Ju 89s set two payload/altitude records, first by carrying 5,000 kg (11,000 lb) to 9,312 m (30,500 ft) and then 10,000 kg (22,000 lb) to 7,242 m (23,750 ft). Both aircraft were later impressed into the Luftwaffe for use as heavy transports. During testing, Lufthansa expressed an interest in an airliner to be developed from the type, which led Junkers to rebuild the incomplete third prototype as the Junkers Ju 90.

Both Ju 89 prototypes seem to have been scrapped by the end of 1939 although some sources claim that they were still in use the following year in Norway.
