Kačice is a municipality and village in Kladno District in the Central Bohemian Region of the Czech Republic. It has about 1,200 inhabitants.

The surname of the first inhabitant of the village was probably Kačice and the village was named after him. The surname was derived from the feminine name Káča, Kačena (variation of the name Kateřina, Czech form of Catherine) or from of the Old Czech word kačice ('duck').

Kačice is located about 8 kilometres (5 mi) west of Kladno and 27 km (17 mi) northwest of Prague. It lies in the Džbán range. The highest point is at 435 m (1,427 ft) above sea level. The Loděnice River flows along the southwestern municipal border.

The first written mention of Kačice is from 1318. Until 1550, it was owned by various lower noblemen. In 1550–1551, both parts of Kačice were bought by the Martinic family and annexed to the Smečno estate.
