We present the first Chandra/ACIS-I X-ray images of the supergiant Galactic HII/starforming region NGC 3603. We resolve the emission into (conservatively) ~ 100 stellar objects, and compare our high resolution Chandra X-ray images of the core cluster to high-resolution optical images obtained by HST. The detected sources apparently include most of the massive O stars, some WR stars (which may show evidence of emission produced in wind-wind collisions), and some surprisingly bright emission from relatively late type stars and PMS stars. We present preliminary source identifications from comparison with optical images and present a preliminary Lx}/L{bol relation for the massive X-ray sources.
