We present the first high-spatial resolution near-infrared (NIR) imaging ofNGC 604, obtained with the NICMOS camera aboard the Hubble Space Telescope(HST). These NICMOS broadband images reveal new NIR point sources, clusters,and diffuse structures. We found an excellent spatial correlation between the8.4 GHz radio continuum and the 2.2mu-m nebular emission. Moreover, massiveyoung stellar object candidates appear aligned with these radio peaks,reinforcing the idea that those areas are star-forming regions. Three differentscaled OB associations are recognized in the NICMOS images. The brightest NIRsources in our images have properties that suggest that they are red supergiantstars, of which one of them was previously known. This preliminary analysis ofthe NICMOS images shows the complexity of the stellar content of the NGC 604nebula.
