We report the discovery of WASP-13b, a low-mass MP = 0.46+0.06-0.05 transiting exoplanet with an orbital period of 4.35298 0.00004 days. The transit has a depth of 9 mmag, and although our follow-up photometry does not allow us to constrain the impact parameter well (0 < b < 0.46), with radius in the range RP ~ 1.06-1.21 RJ the location of WASP-13b in the mass-radius plane is nevertheless consistent with H/He-dominated, irradiated, low core mass and core-free theoretical models. The G1V host star is similar to the Sun in mass (M* = 1.03+0.11-0.09 M⊙ and metallicity ([M/H] = 0.0± 0.2), but is possibly older (8.5+5.5-4.9 Gyr).
