We present high-resolution X-ray images taken with the Chandra X-ray Observatory of the field that contains the unidentified TeV gamma-ray source HESS J1804-216. Among the sources detected, only one is significantly extended. The source is about 40" away from the radio pulsar PSR J1803-2137. The X-ray spectrum of the new source can be fitted well with a power law, although the model is not well constrained due to large statistical uncertainties. The spectrum seems to be very hard, with the best-fit photon index about 1.2. We argue that the source is likely the X-ray counterpart of HESS J1804-216, based on the fact that the Galactic TeV gamma-ray sources are predominantly shell-type supernova remnants or pulsar wind nebulae.
