We report two microlensing events, KMT-2017-BLG-1038 and KMT-2017-BLG-1146, that are caused by planetary systems. These events were discovered by Korea Microlensing Telescope Network survey observations from the 2017 bulge season. The discovered systems consist of a planet and host star with mass ratios of 5.3_–0.4^+0.2×10^–3 and 2.0_–0.1^+0.6×10^–3, respectively. Based on a Bayesian analysis assuming a Galactic model without stellar remnant hosts, we find that the planet KMT-2017-BLG-1038Lb is a super-Jupiter-mass planet (M_p=2.04_–1.15^+2.02M_J) orbiting a mid-M dwarf host (M_h=0.37_–0.20^+0.36M_☉) that is located at 6.01_–1.72^+1.27 kpc toward the Galactic bulge. The other planet, KMT-2017-BLG-1146Lb, is a sub-Jupiter-mass planet (M_p=0.71_–0.42^+0.80M_J) orbiting a mid-M dwarf host (M_h=0.33_–0.20^+0.36M_☉) at a distance of 6.50_–2.00^+1.38 kpc toward the Galactic bulge. Both are potentially gaseous planets that are beyond their hosts' snow lines. These typical microlensing planets will be routinely discovered by second-generation microlensing surveys, rapidly increasing the number of detections.
