Marszowice is a village in the administrative district of Gmina Oława, within Oława County, Lower Silesian Voivodeship, in south-western Poland. It lies approximately 6 km west of Oława and 25 km south-east of the regional capital Wrocław. The name of the settlement is derived from the Polish word marsz, which means "march", in reference to marches when horses were herded to pasture. A 10th-century sword was found in the village, now in the collection of a museum in Wrocław.
