'''334 Chicago''' is a very large [[Asteroid belt|main-belt]] [[asteroid]]. It is classified as a [[C-type asteroid]] and is probably composed of [[carbon]]aceous material.
It was discovered by [[Max Wolf]] on 23 August 1892 in [[Heidelberg]].
During 1999, the asteroid was observed [[Stellar occultation|occulting a star]]. The resulting [[Chord (astronomy)|chords]] provided a cross-section diameter estimate of 174.1&nbsp;km.<ref name=Shevchenko_Tedesco_2006/>
