High and low resolution spectra of the Large Magellanic Cloud (LMC) star HD 269546 were obtained. This star has often been classified as B31p or B41 + WN. The shape of the observed UV spectral energy distribution is discussed in light of this classification. The spectrum is seen to rise towards shorter wavelengths, confirming other results. It is devoid of strong emission features except for He II lambda 1640 and geocoronal H I lambda 1216. Absorption occurs over a wide range of velocities for most of the species shown. Two main components of absorption exist at roughly 0 km/sec and 270 km/sec. The first of these arises in our own galaxy, while the latter is due to Large Magellanic Cloud gas. Si III and S III seem to absorb over the entire velocity range from O km/sec to 300 km/sec without an obvious component structure being visible.
