The Faint Object Spectrograph has been used to obtain a prism spectrum of the pulsar B0540-69, located in the Large Magellanic Cloud. The spectrum, covering 2500--5500 Angstroms, shows a smooth continuum with several broad emission lines. While the lines are produced by the surrounding nebula, the time-averaged emission from the pulsar is the dominant source of the continuum. The observed spectral index of the continuum is alpha = -2.5 +/- 0.2 between 2500 and 4500 Angstroms. Using E(B-V) = 0.20 +/- 0.05 mag gives an unreddenned spectral index of alpha_ {o} = -1.6 +/- 0.4. This is significantly different from the Crab pulsar (alpha_ {o} = 0.11 +/- 0.13), which is the only other pulsar with a measured optical spectrum.
