Dolní Břežany is a municipality and village in Prague-West District in the Central Bohemian Region of the Czech Republic. It has about 4,700 inhabitants.

The villages of Jarov, Lhota and Zálepy are administrative parts of Dolní Břežany.

The name Břežany is derived from the word břeh ('[river] bank' in Czech, but in old Czech also meaning 'hillside') or from the word březí ('birch forest'). The word břežané denoted people who live near a bank, hillside or birch forest, so Břežany was a village of such people. In the 17th century, when church owned two villages named Břežany and needed to distinguish them, this village became known as Dolní ('lower') Břežany.

Dolní Břežany is located south of Prague, in its immediate vicinity. Most of the municipal territory lies in the Prague Plateau. The northwestern part lies in a tip of the Brdy Highlands and includes the highest point of Dolní Břežany, the hill Závist at 389 m (1,276 ft) above sea level. The Vltava River flows along the western municipal border. The brook Břežanský potok flows across the municipality into the Vltava and supplies several small fishponds.

The first written mention of Břežany is from 1332. In 1364, Břežany and Lhota were acquired by the bishopric in Litomyšl, then they were owned by the Zbraslav Monastery. In 1436, King Sigismund pledged the estate to Bened of Nečtiny. Then the owners changed frequently. Between 1627 and 1632, the village changed its name to Dolní Břežany. From 1683 to 1715, Dolní Břežany was property of the Trauttmansdorff family, who sold it to the Prague archbishopric. The Prague archbishops owned it until 1945.
