Radějovice is a municipality and village in Prague-East District in the Central Bohemian Region of the Czech Republic. It has about 500 inhabitants.

The village of Olešky is an administrative part of Radějovice.

The name is derived from the personal name Raděj, meaning "the village of Raděj's people".

Radějovice is located about 10 kilometres (6 mi) southeast of Prague. It lies in the Benešov Uplands. The highest point is at 456 m (1,496 ft) above sea level.

The first written mention of Radějovice is from 1227. In 1228, the village was documented as the possession of the Benedictine St. George's Convent at Prague Castle. Then the village was divided into several parts, owned by different nobles. This state lasted for several centuries until the establishment of a sovereign municipality in 1848.
