Obrnice (German: Obernitz) is a municipality and village in Most District in the Ústí nad Labem Region of the Czech Republic. It has about 2,000 inhabitants.

The villages of České Zlatníky and Chanov are administrative parts of Obrnice.

The initial name of the village was probably Obornice and originated from the word obora (i.e. 'game reserve'), meaning "the village near a game reserve".

Obrnice is located about 2 kilometres (1 mi) east of Most and 29 km (18 mi) southwest of Ústí nad Labem. It lies in the Central Bohemian Uplands. The Bílina River flows through the municipality. The highest point is the hill Zlatník at 522 m (1,713 ft) above sea level. The hill and its surroundings is protected as a national nature reserve.

The first written mention of Obrnice is from 1282, when the village was donated to the monastery in Osek. Except for the years 1420–1460 and 1620–1629, when it passed into the hands of various nobles, the village was owned by the monastery. In the 19th century, mining of lignite developed in the region, which also meant an influx of residents to Obrnice. Brickworks were established here and more workers were coming here. The railway was built in 1871.
