We present an analysis of the Far Ultraviolet Spectroscopic Explorer (FUSE) spectra of the little-known southern nova-like cataclysmic variable, BB Doradus. The spectrum was obtained as part of our Cycle 8 FUSE survey of high-declination nova-like stars. The FUSE spectrum of BB Dor, observed in a high state, is modeled with an accretion disk with a very low inclination (possibly lower than 10°). Assuming an average white dwarf (WD) mass of 0.8 M_☉ leads to a mass accretion rate of 10^–9 M_☉/yr and a distance on the order of ∼650 pc, consistent with the extremely low Galactic reddening in the direction of BB Dor. The spectrum presents some broad and deep silicon and sulfur absorption lines, indicating that these elements are overabundant by 3 and 20 times solar, respectively.
