Poland is a country in Central Europe, situated between the Baltic Sea in the north and two mountain ranges (the Sudetes and Carpathian Mountains) in the south. Since the fall of communism many major companies have been established in Poland. The following list includes both fully Polish companies and foreign owned firms with independent Polish operations, such as Fiat Poland. Most of Poland's economy since communism has been developed by small and medium businesses, but large corporations still control aspects of heavy industry, mining, and chemical refining.
