Jan Becher is a Czech liqueur company headquartered in Karlovy Vary. The most famous product of Becher is Becherovka.

The company Jan Becher — Karlovarská Becherovka, a.s., dates back 200 years to the first decade of the 19th century. In 1807, Josef Becher, a pharmacist from Karlovy Vary (then called Karlsbad), started selling bitters made to his own recipe as a medicinal tonic. In 1841, Josef Becher passed on his budding business to his son and heir Johann. Johann started large-scale production, and accordingly his name has been associated with Becherovka to the present day. The drink was called Karlsbader Becherbitter.

The name Becherovka was developed after World War I, when Bohemia became part of Czechoslovakia, and the sole official language Czech.
