We present the discovery of two transiting exoplanets. HAT-P-28b orbits a V = 13.03 G3 dwarf star with a period P = 3.2572 days and has a mass of 0.63 ± 0.04 M J and a radius of 1.21 +0.11 − 0.08 R J yielding a mean density of 0.44 ± 0.09 g cm −3 . HAT-P-29b orbits a V = 11.90 F8 dwarf star with a period P = 5.7232 days and has a mass of 0.78 +0.08 − 0.04 M J and a radius of 1.11 +0.14 − 0.08 R J yielding a mean density of 0.71 ± 0.18 g cm −3 . We discuss the properties of these planets in the context of other known transiting planets.
