We report the discovery by the CoRoT satellite of a new transiting giant planet in a 2.83 days orbit about a V=15.5 solar analog star (M_* = 1.08 ± 0.08 M_sun, R_* = 1.1 ± 0.1 R_sun, T_eff = 5675 ± 80 K). This new planet, CoRoT-12b, has a mass of 0.92 ± 0.07 M_Jup and a radius of 1.44 ± 0.13 R_Jup. Its low density can be explained by standard models for irradiated planets.
