Dětřichov (German: Dittersdorf) is a municipality and village in Svitavy District in the Pardubice Region of the Czech Republic. It has about 400 inhabitants.

The original Latin name of the village was Theodriciuilla. It was derived from the personal German name Dietrich (Czech: Dětřich), latinized as Theodericus, meaning "Dietrich's village". The Czech and German names were created by translation. The German name later appeared as Dittersdorf.

Dětřichov is located about 6 kilometres (4 mi) northeast of Svitavy and 59 km (37 mi) southeast of Pardubice. It lies in the Svitavy Uplands. The highest point is a nameless hill at 641 m (2,103 ft) above sea level.

The first written mention of Dětřichov is from 1167. In 1278, the area was colonized by German settlers. The hamlet of Vysoké Pole, nowadays a local part of Dětřichov, was founded in 1777. After World War II, the German population was expelled and partially replaced by Czechs.
