Rajcza [ˈrai̯t͡ʂa] is a village in Żywiec County, Silesian Voivodeship, in the historic province of Lesser Poland, close to the border with Slovakia.

The village of Rajcza was founded in the first half of the 17th century, when this area belonged to Kraków Voivodeship, of the Polish - Lithuanian Commonwealth.

At that time Rajcza belonged to Queen Constance of Austria, the wife of King Sigismund III Vasa, part of her folwark with main center located at Węgierska Górka.

In 1843, iron manufacture was opened here, and 1854–1894, the owner of the village, Teodor Primavesi, remodeled a local palace, establishing a park around it.

In 1884 Rajcza got rail connection with Żywiec and Cadca, and 10 years later, the village was purchased by the Lubomirski family, who expanded the palace.
