A compact and bright radio and infrared source within the starburst center of the dwarf galaxy NGC 5253 appears to be an extremely large compact HII region. The high density (ne ~ few xlO4 cm-3) and size (∼1-2 pc) of the nebula require the ionization equivalent of at least 4000 O7 stars. We suggest that this optically obscured nebula is a forming super star cluster, or protoglobular cluster, with an age of a few hundred thousand years.
