449 Hamburga is a carbonaceous asteroid from the background population of the intermediate asteroid belt, approximately 75 kilometers in diameter. It was discovered by German astronomers Max Wolf and Friedrich Schwassmann at Heidelberg Observatory on 31 October 1899, and later named after the city of Hamburg in Germany.[3][2]

449 was a proposed target for the 1980s-1990s space probe mission proposal CRAF.
