Bohemian glass, also referred to as Bohemia crystal, is glass produced in the regions of Bohemia and Silesia, now parts of the Czech Republic. It has a centuries long history of being internationally recognised for its high quality, craftsmanship, beauty and often innovative designs. Hand-cut, engraved, blown and painted decorative glassware ranging from champagne flutes to enormous chandeliers, ornaments, figurines and other glass items are among the best known Czech exports and immensely popular as tourist souvenirs. The Czech Republic is home to numerous glass studios and schools attended by local and foreign students.

The oldest archaeological excavations of glass-making sites in the region date to around 1250 and are located in the Lusatian Mountains of Northern Bohemia. Other notable Czech sites of glass-making throughout the ages are Skalice (German: Langenau), Jablonec nad Nisou, Železný Brod, Poděbrady, Karlovy Vary, Kamenický Šenov (German: Steinschönau) and Nový Bor (German: Haida). Several of these towns have their own glass museums with many items dating to around 1600. Jablonec nad Nisou in particular is famous for the local tradition of manufacturing glass costume jewellery. Its long history is documented by large collections in the Museum of Glass and Jewellery in Jablonec nad Nisou.

Among the most famous Czech glass producers are: Moser (considered the most luxurious Czech brand), Rückl (the glass from them is owned, for example, by the British Queen Elizabeth II), and Crystalex (the largest Czech producer of drinking glasses, own trademark Bohemia Crystal).
