Interflug GmbH (; ) was the national airline of East Germany (officially the “German Democratic Republic”) from 1963 to 1991. Based in East Berlin, it operated scheduled and chartered flights to European and intercontinental destinations out of its airline hub at Berlin Schönefeld Airport, focusing on Comecon countries. Interflug also had significant crop dusting operations. Following German reunification, the company was liquidated.
The airline's route network and fleet of Soviet-built aircraft grew significantly in the 1960s. The Ilyushin Il-18 turboprop airliner became the workhorse of Interflug's Flight length flights during that period. The company had been the intended primary operator of the Baade 152, an early jet age constructed in East Germany. Its development never went beyond the prototype phase and was abandoned in 1961. In 1969, the Tupolev Tu-134 was introduced, the first jet airliner operated by Interflug, used on European routes. The long-range Il-62 joined the fleet in 1971. That same year, the number of Interflug passengers reached 1 million. At its peak, Interflug flew to destinations such as Havana, Cuba, Singapore and Conakry, Guinea.
As a result of the 1970s energy crisis and increasing fuel prices, Interflug gradually dismantled its domestic route network. The last scheduled domestic flight, to transport prisoners from East Berlin to Erfurt, took place in April 1980.
The first Airbus A310 was delivered to Interflug on 26 June 1989. The East German crews for the new aircraft type were trained in West Germany; aircraft maintenance was also performed there. The A310 enabled non-stop flights to Cuba (flights had previously required a fuel stop at Gander International Airport in Canada).
Following the fall of the Berlin Wall on 9 November 1989 and the subsequent political upheaval in East Germany, several airlines expressed interest in buying parts of the highly unprofitable company to secure a share of the German air traffic market, especially in Berlin. In early March 1990, Lufthansa signed a letter of intent to acquire 26 percent of Interflug, but the offer was blocked by Germany's Federal Cartel Office. Plans for a takeover by British Airways did not materialize either (the UK airline instead founded Deutsche BA in 1992). On 1 July 1990, Interflug became a member of the International Air Transport Association (IATA).
As a consequence of German reunification on 3 October 1990, Interflug came under the administration of the Treuhandanstalt, along with all other East German state property. As no buyers could be found, the liquidation of Interflug, which had 2,900 employees and 20 aircraft at the time, was announced on 7 February 1991. The airline was then dismantled. The last commercial flight (on the Berlin-Vienna-Berlin route, using a Tu-134) took place on 30 April 1991.
The three Airbus A310 purchased by Interflug in 1988 were handed over by the Treuhandanstalt to the Federal Republic of Germany and became part of the German Air Force, used for VIP transport of high-ranking politicians like the German president or chancellor.
Several former Interflug aircraft have been preserved in different places in Germany.

By the early 1980s, low Interflug ticket prices led to a severe decline in holiday flights at Berlin Tegel Airport in West Berlin. Pilots at Pan Am, which had a hub at Tegel, reportedly considered operating flights to Greece without pay to allow the airline to compete with Interflug.
Interflug signed an agreement with Turkish Airlines giving the two airlines exclusive rights to offer dedicated flights for Turkish Gastarbeiter to and from West Germany and West Berlin. In the 1980s, Interflug set up a partnership with KLM for a joint operation on the East Berlin-Amsterdam route. Of the six weekly flights, two were operated by KLM's Fokker F28 Fellowships, and four by Interflug's Tu-134s and Il-62s. As neither airline was allowed to cross the intra-German border, the KLM flights were routed via Denmark, and Interflug used a southern routing over Czechoslovakia.
During the annual Leipzig Trade Fair, at that time considered the most important meeting place for businesspeople and politicians from both sides of the Iron Curtain, Lufthansa and Interflug were granted special permits to operate flights between Leipzig and West Germany. In 1986, Lufthansa and Interflug applied for joint traffic rights for year-round scheduled intra-German flights over the Iron Curtain, which were initially rejected by the Western Bloc (likely due to concerns that their unique market position for flights to and from Berlin might be weakened), and only granted in August 1989. Interflug was then able to launch flights on the Leipzig-Düsseldorf route, while Lufthansa began serving the Frankfurt-Leipzig leg. In 1990, Interflug added flights from Dresden to Hamburg and Cologne.
