In apparent contrast, about two percent of the WR stars in the Galaxy, the LMC and M33 simultaneously display strong lines of carbon and nitrogen, i.e. they are transition type WN/C or WC/N stars. We report here the serendipitous discovery of M31 WR 84-1, the first transition star in M31, located at RA = 00:43:43.61 DEC = +41:45:27.95 (J2000). We present its spectrum, classify it as WN5/WC6, and compare it with other known transition stars.
