Chrast (Czech pronunciation: [ˈxrast]) is a town in Chrudim District in the Pardubice Region of the Czech Republic. It has about 3,100 inhabitants. The historic centre with the castle complex is well preserved and is protected by law as an urban monument zone.

The villages of Chacholice, Podlažice and Skála are administrative parts of Chrast.

Chrast is located about 11 kilometres (7 mi) southeast of Chrudim and 18 km (11 mi) southeast of Pardubice. It lies in the Svitavy Uplands. The highest point is the elevated plain of Kostecká hůra at 432 m (1,417 ft) above sea level. The town is situated on the right bank of the Žejbro Stream. Horecký Pond is located south of the town.

The slope on the right bank of the stream is protected as the Chrašická stráň Nature Monument.

The oldest part of Chrast is Podlažice. The Benedictine monastery in Podlažice was founded in 1159. The monastery is where the Codex Gigas (or "Devil's Bible") was produced. It remains the largest extant medieval manuscript. However, it is unlikely that the book was written at the monastery due to its small size and meagre funds.

The first written mention of Chrast is from 1318. It was founded in the second half of the 13th century by monks from the Podlažice Monastery. The monastery was destroyed by the Hussites in 1421.

In 1539, Chrast was acquired by the noble Slavata of Chlum and the Košumberk family. In the early 17th century, Albrecht Slavata had built a castle here. In 1664, Chrast was bought by Hradec Králové Bishopric. The castle served as the summer residence of several bishops. In the 18th century, it was rebuilt and extended. In 1853, Chrast was promoted to a town.
