We report the discovery of four transiting extrasolar planets (HAT-P-34b -- HAT-P-37b) with masses ranging from 1.05 to 3.33 MJ and periods from 1.33 to 5.45 days. These planets orbit relatively bright F and G dwarf stars (from V = 10.16 to V = 13.2). Of particular interest is HAT-P-34b which is moderately massive (3.33 MJ), has a high eccentricity of e = 0.441 ±0.032 at P = 5.4526540±0.000016 d period, and shows hints of an outer component. The other three planets have properties that are typical of hot Jupiters.
