Sedlec is a municipality and village in České Budějovice District in the South Bohemian Region of the Czech Republic. It has about 500 inhabitants. The centres of the villages of Malé Chrášťany and Plástovice within the municipality are protected as two village monument reservations.

The villages of Lékařova Lhota, Malé Chrášťany, Plástovice and Vlhlavy are administrative parts of Sedlec.

The name is common in the Czech Republic. It is derived from the Czech word sedlo, which means 'saddle' in modern Czech, but also 'village' in old West Slavic languages.

Sedlec is located about 18 kilometres (11 mi) northwest of České Budějovice. It lies in a flat landscape in the České Budějovice Basin. The stream Bezdrevský potok flows through the municipality.

There are several fishponds in the municipal territory; the largest of them are Volešek with an area of 134.4 hectares (332 acres) and Vlhlavský rybník with an area of 91.7 hectares (227 acres).

The first written mention of Sedlec is from 1394. Until the 16th century, the village was owned by various lower noblemen. In the 1563, it was bought by William of Rosenberg and joined to the Libějovice estate. The local fortress ceased to serve as the seat of the nobility and was demolished in 1564. After the Battle of White Mountain in 1620, the estate was donated to Charles Bonaventure, Count of Bucquoy. Then the estate was acquired by the Schwarzenberg family, which owned Sedlec until the establishment of an independent municipality in 1848.
