We report on the observation of PSR 2334+61 in the soft X-ray domain with ROSAT. Assuming a power-law spectrum $dN/dE\propto E^{-\alpha}$ with photon-index $\alpha=2$ we derive an X-ray flux of $f_x=(7.1 \pm 0.2) \times 10^{-14} \hbox{erg s}^{-1}\hbox{cm}^{-2}$ within the $0.1$--$2.4$ keV energy range. An upper limit for the neutron star's surface temperature is put at $T_s^\infty \sim 1.2\times 10^6$ K for a neutron star with a medium stiff equation of state (FP-model with $M=1.4$ \Mo, $R=10.85$ km). Slightly different values for $T_s^\infty$ 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 G114.3+0.3 associated with PSR 2334+61.
