Józef Zachariasz Bem (, ; March 14, 1794 – December 10, 1850) was a Polish engineer and general, an Ottoman pasha and a national hero of Poland and Hungary, and a figure intertwined with other European patriotic movements. Like Tadeusz Kościuszko (who fought in the American War of Independence) and Jan Henryk Dąbrowski (who fought alongside Napoleon Bonaparte in Italy and in the French Invasion of Russia), Bem fought outside Poland's borders anywhere his leadership and military skills were needed.
