Many of the properties of massive stars in external galaxies, such aschemical compositions, mass functions, and ionizing fluxes, can be derived fromthe study of the associated clouds of ionized gas. Moreover, the signatures ofWolf-Rayet stars are often detected in the spectra of extragalactic H IIregions. This paper reviews some aspects of the recent work on the massive starcontent of nearby spiral galaxies, as inferred from the analysis of giant H IIregions. Particular attention is given to regions of high metallicity,including nuclear hot spots, and to the chemical abundance comparison betweensupergiant stars and ionized gas.
