Franciszek Bujak (16 August 1875, in Maszkienice near Brzesko - 21 March 1953, in Kraków) was a Polish academic and historian of economic, political and social history of Poland.

Bujak was active politically in the Polish People's Party "Piast" (PSL) and the Stronnictwo Ludowe.

Bujak first groundbreaking analysis of the economic development generated by a village during the Partitions of Poland was published under the title Żmiąca wieś powiatu limanowskiego.

The remaining land was parceled, as at least 80 percent of families in Ropczyce County were sent remittance from America prior to World War I. Bujak called this economic process "a victory of smallholders", crediting American émigrés and their money.

Polish smallholders in Ropczyce County could at the time only go to Prussia or Moravia to work in the seasonal industry, therefore their monetary contribution was insignificant.
