We report the discovery of three new transiting extrasolar planets orbiting moderately bright (V=11.1 to 12.4) F stars. The planets have periods of P = 2.6940 d to 4.4572 d, masses of 0.60 Jupiter masses to 0.80 Jupiter masses, and radii of 1.57 Jupiter radii to 1.73 Jupiter radii. They orbit stars with masses between 1.40 solar masses and 1.51 solar masses. The three planets are members of an emerging population of highly inflated Jupiters with 0.4 Jupiter masses < M < 1.5 Jupiter masses and R > 1.5 Jupiter radii.
