The Venezuelan species of the genus Gyrinus Geoffroy, 1762 are reviewed (Gyrinidae: Gyrininae: Gyrinini). The Venezuelan Gyrinus fauna is found to be comprised of nine species distributed among the subgenera Neogyrinus Hatch, 1926 and Oreogyrinus Ochs, 1935, although Gyrinus (Oreogyrinus) colombicus Régimbart, 1883 is known from imprecisely localized and potentially mislabeled specimens and the species presumably does not occur in Venezuela. Three new species are described: G. (Oreogyrinus) vinolentus sp. nov. from the Andes, and G. (Oreogyrinus) iridinus sp. nov. and G. (Neogyrinus) sabanensis sp. nov., from the Guiana Shield region. Two new synonymies are established: G. amazonicus Ochs, 1958 syn. nov. is synonymized with G. guianus Ochs, 1935, and G. racenisi Ochs, 1953 syn. nov. is synonymized with G. ovatus Aubé, 1838. Gyrinus (Oreogyrinus) feminalis Mouchamps, 1957, described from Venezuela from two female syntypes only, is considered as species inquirendum, as the types were not found. For each species a dorsal habitus, illustration of male and female genitalia, and distribution map are provided. A key and checklist for the Venezuelan Gyrinus species is included.
