Oldřichovice (Třinec)

 Oldřichovice  (Polish: Oldrzychowice , German: Oldrzichowitz) is a village in Frýdek-Místek District, Moravian-Silesian Region, Czech Republic. It was a separate municipality but became administratively a part of Třinec in 1980. It has a population of 3,182 (1 January 2008). and lies in the historical region of Cieszyn Silesia. Tyrka flows through the village.

The name of the village is of patronymic origins derived from personal name Oldrzych, from German name Ulrich.

The settlement was first mentioned in a Latin document of Diocese of Wrocław called Liber fundationis episcopatus Vratislaviensis from around 1305 as item in Ulrici villa. It meant that the village was in the process of location (the size of land to pay a tithe from was not yet precised). The creation of the village was a part of a larger settlement campaign taking place in the late 13th century on the territory of what will be later known as Upper Silesia.
