                                   ABSTRACT
    
    We present CCD photometry and spectroscopy for stars in Lucke-Hodge 58,
    an isolated OB association in the Large Magellanic Cloud (LMC)
    northwest of 30 Doradus.  The photometric catalog contains 839 stars
    with UBV magnitudes complete to V approx. 19.  We have obtained spectra
    and classified 35 stars; combined with previous published spectral
    types, we find 22 O-type stars.  The earliest type is O3-4 V, and there
    are three WR stars in the association.  The slope of the initial mass
    function, Gamma = -1.7 +/- 0.3, is in good agreement with other LMC
    associations.  The presence of several evolved supergiants with masses
    about 15-25 Msun suggests that some star formation took place as early
    as 10 million years ago, but the majority of stars formed coevally
    within the past few million years.
