IUE data are presented on the massive binary system HD 152667 (spectral type BO I), covering many phases of the 8 day orbit. Low-dispersion data are used to drive T(eff), E(B-V), and the UV light curve. The secondary object is much fainter than the primary at all wavelengths. The stellar wind shows complex multiple components and appears to be unique. A weak, variable distortion of the wind may be present near superior conjunction of the primary. Weak lines show the primary orbital motion, with minor distortions. The interstellar absorption spectrum shows high temperature species most probably arising in the H II region produced by the star. No clear evidence is found regarding the nature of the secondary object. Discrepancies in published ephemerides of the system are clarified.
