The recently discovered radio pulsar PSR J1718-37184 has an inferred dipolar magnetic field strength of 7.4x1013 G. This is higher than that inferred for the well-known ``Anomalous X-ray Pulsar,'' 1E 2259+586, which is thought to be a magnetar. Here we report on a serendipitous Chandra X-ray Observatory detection of this pulsar. We show that the pulsar's X-ray luminosity is consistent with that expected simply from initial cooling of a young neutron star. Thus, in spite of the apparently magnetar-strength field in this radio pulsar, it shows no evidence for any magnetar-like emission. We discuss the implications for the magnetar model.
