Teschener Mundarten
Cieszyn Vlachs (, ) are a Polish ethnographic group (subgroup of Silesians) living around the towns of Cieszyn and Skoczów, one of the four major ethnographic groups in Cieszyn Silesia, the one mostly associated with wearing Cieszyn folk costume but not the only one speaking Cieszyn Silesian dialect. The name, identical to Vlachs (), is probably not directly associated with that group (as Gorals are) but was coined by adjacent groups as a nickname.
