    334 Chicago is a very large main-belt asteroid. It is classified as a C-type asteroid and is probably composed of carbonaceous material.

    It was discovered by Max Wolf on 23 August 1892 in Heidelberg.

    During 1999, the asteroid was observed occulting a star. The resulting chords provided a cross-section diameter estimate of 174.1 km.
