We report the discovery of three new transiting extrasolar planets orbiting moderately bright (V = 11.1, 11.7, and12.4) F stars. The planets HAT-P-39b through HAT-P-41b have periods of P = 3.5439days, 4.4572days, and 2.6940days, masses of 0.60M J,0.62M J, and 0.80M J, and radii of 1.57R J,1.73R J, and 1.68R J, respectively. They orbit stars with masses of 1.40M ,1.51M , and 1.51M , respectively. The three planets are members of an emerging population of highly inflated Jupiters with 0.4 M J < M < 1.5 M J and R > 1.5 R J.
