Gnesta is a town in Södermanland in Sweden. The town itself has around 5,500 inhabitants; half the population of the municipality, Gnesta kommun.
Gnesta was built at the main rail line between Stockholm and Gothenburg. Nowadays, much of the population commutes to Stockholm or nearby Södertälje.
Some scenes of the Swedish film The Girl With the Dragon Tattoo were filmed in Gnesta.
