We report on the observation of PSR 2334+61 in the soft X-ray domain with ROSAT. Assuming a power-law spectrum dN/dE∝E^–α with photon-index α=2 we derive an X-ray flux of f_x=(7.1±0.2)x10^–14erg/s/cm² within the 0.1-2.4keV energy range. An upper limit for the neutron star's surface temperature is put at T_s^∞∼1.2x10⁶K for a neutron star with a medium stiff equation of state (FP-model with M=1.4M_☉, R=10.85km). Slightly different values for T_s^∞ are computed for the various neutron star models available in the literature, reflecting differences in the equation of state. No soft X-ray emission is detected from the supernova remnant G 114.3+0.3 associated with PSR 2334+61.
