449 Hamburga is a large Main belt asteroid that was discovered by German astronomers Max Wolf and A. Schwassmann on October 31, 1899 in Heidelberg. It is classified as a C-type asteroid and is probably composed of carbonaceous material.

In the 1990s, NASA considered a spacecraft mission to the asteroid, including a tie-in with McDonald's.[4]

It was predicted that 449 occulted the star HIP 1424 in July 2013.[5]
