We report on ASCA observations of the radio pulsar/Be star binary PSR B1259$-$63 made at three epochs around the most recent periastron passage. The pulsar was clearly detected at all three epochs, with the X-ray emission characterized by a power-law spectrum, modest luminosity, modest photoelectric absorption, and absence of detectable pulsations. We interpret these results as non-thermal shock-powered emission produced by the interaction of the relativistic pulsar wind with the Be star circumbinary material.
