The Ropičanka (Polish: Ropiczanka) is a 16 kilometres (9.9 mi)-long river in the Frýdek-Místek and Karviná districts, Moravian-Silesian Region, Czech Republic. It is a left tributary of the Olza River, which it enters on the outskirts of Český Těšín. The Ropičanka flows through Řeka, Smilovice, Střítež and Ropice (from source to mouth). A small portion of its volume (about 0.07 m³/s or 2.5 ft³/s) is diverted to the watershed of the Stonávka River in order to increase the flow rate at the Těrlicko Dam.
