The semi-detached eclipsing binary system BP Muscae has been analysed using the Wilson-Devinney program. Light curves have been obtained in the Geneva 7-colour photometric system, and radial velocity curves for both components have been measured with the spectrograph Coralie. The physical and orbital parameters have been determined through a self-consistent simultaneous solution of light curves in seven colours and of the radial velocity curves of both components. The absolute elements of the components are, for the primary (mass gainer), , , , K, and for the secondary (mass loser), , , , K. The semi-major axis A of the relative orbit is . The spectral type of the components are A0.5/1.5 V (primary) and about G5 III. The distance to BP Mus is evaluated as pc, and the colour excess E[B2-V1] as .
