We report the discovery of three moderately high-mass transiting hot Jupitersfrom the HATSouth survey: HATS-22b, HATS-23b and HATS-24b. These planets add tothe numbers of known planets in the ~2MJ regime. HATS-22b is a 2.74+/-0.11 MJmass and 0.953+0.048/-0.029 RJ radius planet orbiting a V = 13.455 +/- 0.040sub-silar mass (M_star = 0.759+/-0.019 M_sun; R_star = 0.759+/-0.019 R_sun)K-dwarf host star on an eccentric (e = 0.079 +/- 0.026) orbit. This planet'shigh planet-to-stellar mass ratio is further evidence that migration mechanismsfor hot Jupiters may rely on exciting orbital eccentricities that bring planetscloser to their parent stars followed by tidal circularisation. HATS-23b is a1.478 +/- 0.080 MJ mass and 1.69 +/- 0.24 RJ radius planet on a grazing orbitaround a V = 13.901 +/- 0.010 G-dwarf with properties very similar to those ofthe Sun (M_star = 1.115 +/- 0.054 M_sun; R_star = 1.145 +/- 0.070 R_sun).HATS-24b orbits a moderately bright V = 12.830 +/- 0.010 F-dwarf star (M_star =1.218 +/- 0.036 M_sun; R_star = 1.194+0.066/-0.041 R_sun). This planet has amass of 2.39 +0.21/-0.12 MJ and an inflated radius of 1.516 +0.085/-0.065 RJ.
