We report the discovery of HAT-P-56b, a transiting high inflated hot-jupiter orbiting a F type star in the field 0 of the NASA K2 mission, by the HATNet survey. We combine ground-based photometric light curves with the high
precision photometry obervation by the K2 mission, as well as radial velocity to determine the physical properties of this system. HAT-P-56b has a mass around ~2.2 Mjunp, a radius of ~1.5 Rjup, and transits its host star with a period of 2.79d. The host star has a V band magnitude of 10.9, Mass of 1.29 Msun, and radius of 1.433 Rsun. The radius of HAT-P-56b is among one of the largest compare to planets with similar mass, making it an interesting target for following up atmospherical observations.
