We report the discovery of a super-Jovian planet in the microlensing event KMT-2016-BLG-1836, which was found by the Korea Microlensing Telescope Network (KMTNet) high-cadence observations (Γ∼4hr^–1). The planet-host mass ratio q ∼ 0.004. A Bayesian analysis indicates that the planetary system is composed of a super-Jovian M_planet=2.2_–1.1^+1.9M_J planet orbiting an M or K dwarf, M_host=0.49_–0.25^+0.38M_☉, at a distance of D_L=7.1_–2.4^+0.8 kpc. The projected planet-host separation is 3.5_–0.9^+1.1 au, implying that the planet is located beyond the snow line of the host star. Future high-resolution images can potentially strongly constrain the lens brightness and thus the mass and distance of the planetary system. Without considering detailed detection efficiency, selection, or publication biases, we find a potential mass-ratio desert at -3.7 <= log q <= -3.0 for the 31 published KMTNet planets.
