Polygrafia (1907 - 1999) was a prolific general printing and publishing house based in Prague (Praha), the Czech Republic in the middle part of the 20th century. Polygrafia emerged out of the Chezh Graphic Union (Česká Grafická Unie). The Polygrafia imprint was active from roughly 1922 to 1999. During the Socialist Era Polygrafia was nationalized and specialized in state propaganda publications. In 1989, their iconic late Art Nouveau headquarters were converted into a luxury hotel.
