Rudzica [ruˈd͡ʑit͡sa] is a village in Gmina Jasienica, Bielsko County, Silesian Voivodeship, southern Poland.

It was a part of a larger settlement campaign taking place in the late 13th century on the territory of what will be later known as Upper Silesia.

The village belonged initially to the Duchy of Teschen, formed in 1290 in the process of feudal fragmentation of Poland and was ruled by a local branch of Piast dynasty.

The village became a seat of a Catholic parish, first mentioned in an incomplete register of Peter's Pence payment from 1335 as villa Rudgeri[4] and as such being one of the oldest in the region.

Rauditz which evolved to Rudzica is of topographic origin and hints of ruddy water in the local river.
