Broad band J, H and K magnitudes are presented for 33 blue and red supergiants within the central 12 arcmin of the 30 Doradus complex. Band strength indices for the 2.3 micron CO bands are given, and mass loss rates are derived for the 30 Dor Wolf-Rayet stars. The resulting high rates of mass loss place severe limits on the age of the blue population, and the broad band colors of the late-type supergiants differ from colors of galactic stars of the same luminosity, which may be evidence of metal deficiencies in the 30 Dor supergiants. The CO band strengths of the late-type supergiants are weaker than those of the galactic supergiants at a given temperature, and the possible causal relationship between the two stellar populations is discussed in terms of recent theories of OB star formation.
