Žerčice a municipality and village in Mladá Boleslav District in the Central Bohemian Region of the Czech Republic. It has about 400 inhabitants.

The name is probably derived from the personal name Žirka, meaning "the village of Žirka's people". The oldest form of the name was Žrčinaves.

Žerčice is located about 9 kilometres (6 mi) southeast of Mladá Boleslav and 48 km (30 mi) northeast of Prague. It lies on the border between the Jičín Uplands and Jizera Table. The highest point is the hill Žlábky at 316 m (1,037 ft) above sea level. The Vlkava River flows through the municipality. There is a system of fishponds in the southern part of the territory.

The first written mention of Žerčice is from 1070, in Chronica Boemorum. The greatest boom of Žerčice occurred during the rule of Hanuš Bryknár of Brukštejn in the early 16th century. The village was promoted to a market town in 1511. In 1621, Žerčice was purchased by the Waldstein family and joined to the Dobrovice estate. In 1639, during the Thirty Years' War, Žerčice was burned down by the Swedish army and ceased to be a market town.
