We have compiled catalogs of Massive Stars in the Magellanic Clouds with all known reliable spectral types as derived from either slit or fiber spectra. These catalogs span the full range of massive star types; Wolf-Rayet stars, LBVs, Be stars, B[e[ stars, supergiants of various types as well as numerous normal main sequence stars. We have cross-correlated these catalogs with data in the Spitzer SAGE catalogs of the LMC and SMC and have found several thousand matches and have constructed color-magnitude and color-color diagrams for the Spitzer data to investigate trends in both galaxies. These data are also used to investigate IR excesses due to stellar winds, circumstellar gaseous disks, and dust around massive stars in the LMC and SMC. We find that LBVs and B[e] stars are among the brightest objects in both galaxies in the IR. Both the input spectral types catalogs and the resulting catalogs of IR magnitudes and flux distributions will be made public.
