Aurora was a rumored mid-1980s United States reconnaissance aircraft. There is no substantial evidence that it was ever built or flown and it has been termed a myth.

Aerospaceweb.org concluded, "The evidence supporting the Aurora is circumstantial or pure conjecture, there is little reason to contradict the government's position."
