        We present an all-sky flux catalog of 760 H II regions with
     angular sizes ranging up to 10' at 4.85 GHz. The data were
     compiled in a self-consistent manner from existing images of
     the Green Bank and Parkes-MIT-NRAO 4.85 GHz radio continuum
     surveys. Nearly 35% of these H II regions have fluxes measured
     from these surveys for the first time. We compared our results
     to the previously published source catalogs which fit the same
     data. The new flux measurements agree within 5%-7% of these
     values and fall well within the formal errors.  The diameters
     fall within 16% of the previously published fits to the same
     data, within the formal uncertainties of these values.
