We present the analysis of a planetary microlensing event OGLE-2019-BLG-0362 with a short-duration anomaly (∼0.4days) near the peak of the light curve, which is caused by the resonant caustic. The event has a severe degeneracy with Δχ2=0.9 between the close and the wide binary lens models both with planet-host mass ratio q≃0.007. We measure the angular Einstein radius but not the microlens parallax, and thus we perform a Bayesian analysis to estimate the physical parameters of the lens. We find that the OGLE-2019-BLG-0362L system is a super-Jovian-mass planet Mp=3.26−0.58+0.83MJ orbiting an M dwarf Mh=0.42−0.23+0.34M⊙ at a distance DL=5.83−1.55+1.04kpc. The projected star-planet separation is a⊥=2.18−0.72+0.58AU, which indicates that the planet lies beyond the snow line of the host star.
