We announce the discovery of a highly inflated transiting hot Jupiter by the KELT-North survey. A global analysis including constraints from isochrones indicates that the V = 10.8 host star (HD 343246) is a mildly evolved, G dwarf with T_(eff)= 5754^(+54)_(-55)K, log g = 4.078^(0.049)_(0.054), [Fe/H] = 0.272 ± 0.038, an inferred mass M_* = 1.211_(0.066)^(+0.078)M_☉, and radius R_*=1.67 _(-0.12)^(+0.14) R_☉. The planetary companion has a mass Mp = 0.867 _(-0.061)^+(0.065) MJ, radius R_p 1.86_…
