The name of the village is of topographic origin, derived from the name of the river Vistula (Polish: Wisła). Some sources claim that the name is connected with the Vistulans tribe, however the village is too young to have existed in the tribal era. The name was mostly Germanised as Wislitz.
Wiślica lies in the southern part of Poland, north of Skoczów, 14 km (9 mi) north-east of the county seat, Cieszyn, 19 km (12 mi) west of Bielsko-Biała, 55 km (34 mi) south-west of the regional capital Katowice, and 14 km (8.7 mi) east of the border with the Czech Republic.
The village is situated on a top of one of the hills of the Silesian Foothills, which height is approximately 360 m (1,180 ft) above sea level, 10 km (6.2 mi) north-west of the Silesian Beskids; The hills rises over the left bank of the Vistula river and its eastern slope is covered by a forest protected as a nature reserve, called Skarpa Wiślicka.
