Lučina (Polish: Łucyna or Łuczyna) is a river in Moravian-Silesian Region in the Czech Republic. It is the tributary of the Ostravice River to which it enters in Ostrava. It originates in the Moravian-Silesian Beskids range and then flows northwestward through Horní Bludovice and Dolní Bludovice, near Havířov. Žermanice Reservoir is built on the river. River is distinct for its meanders which are protected as a nature monument.

The book Most nad Łucyną (The Bridge over the Lučina) by poet Wiesław Adam Berger is centered on the river.
