Aleksander Józef Lisowski HNG (c. 1580 – October 11, 1616) was a Polish noble (szlachcic), commander of a mercenary group that after his death adopted the name "Lisowczycy."

Aleksander Józef Lisowski became one of the leaders of the resulting konfederacja – a mutinied part of the army, that decided to gather their wages by pillaging local civilians, not caring whether they pledged allegiance to Poland-Lithuania or Sweden.

Although this annoyed the Great Hetman of Lithuania Jan Karol Chodkiewicz, and resulted in the banicja sentence on Lisowski, little was done to stop the mutinied forces.

Eventually, after the rokosz forces were defeated in the Battle of Guzow, Lisowski's fortunes turned low and he became persona non grata in most of the Commonwealth and sought refugee with a powerful magnate family of Radziwiłłs.

In the Spring of 1608, together with Aleksander Kleczkowski, leading his forces – a band of few hundred ragtag soldiers of fortune: Don Cossacks, Ruthenians, Tatars, Germans, Swedes, Poles, Lithuanians and who knows who else,[citation needed] he was sent to Ryazan lands to incite uprising against Vasiliy Shuisky.

He reorganized the army and joined with Jan Piotr Sapieha, but besieged and failed to capture the Troitse-Sergieva Lavra fortress and were forced to retreated near Rakhmantsevo.
