Using observations made with the XMM-Newton Observatory, we report the probable X-ray detection of the high-magnetic-field radio pulsar PSR J1734-3333. This pulsar has an inferred surface dipole magnetic field of B = 5.2 x 10{sup 13} G, just below that of one anomalous X-ray pulsar. We find that the pulsar has an absorbed 0.5-2.0 keV flux of (5-15) x 10{sup -15} erg s{sup -1} cm{sup -2} and that its X-ray luminosity L{sub X} is well below its spin-down luminosity E-dot , with L{sub X}<0.1 E-dot . No pulsations were detected in these data although our derived upper limit is unconstraining. Like most of the other high-B pulsars, PSR J1734-3333 is X-ray faint with no sign of magnetar activity. We tabulate the properties of this and all other known high-B radio pulsars with measured thermal X-ray luminosities or luminosity upper limits, and speculate on a possible correlation between L{sub X} and B.
