Świecie (Polish: [ˈɕfjɛt͡ɕɛ] ) is a village in the administrative district of Gmina Leśna, within Lubań County, Lower Silesian Voivodeship, in south-western Poland, near the border with the Czech Republic.

It lies on the southeastern rim of the historic Upper Lusatia region, approximately 5 kilometres (3 mi) south of Leśna and 15 kilometres (9 mi) south of Lubań. The village is located 124 kilometres (77 mi) west of the regional capital Wrocław.

From 1975 to 1998, Świecie was part of Jelenia Góra Voivodeship.

Świecie Castle, situated on a Gneiss rock, was first mentioned in a 1329 treaty between King John of Bohemia, who had been enfeoffed with the Upper Lusatian estates by Emperor Louis IV, and Duke Henry I of Jawor, ruler over the adjacent Lower Silesian lands in the east. The fortress, together with the neighbouring castles at Leśna and Czocha were finally incorporated into the Lands of the Bohemian Crown in 1346.

According to the 1635 Peace of Prague, Świecie passed to the Electorate of Saxony. In 1719 the estates were purchased by the Saxon field marshal Jacob Heinrich von Flemming. Upon the Vienna Congress in 1815, the area was incorporated into the Prussian Province of Silesia.
