Four special elections (known elsewhere as "by-elections") to the National Assembly of the Philippines, the legislature of the Commonwealth of the Philippines, were done on September 1, 1936. These were to fill up vacancies from four seats.
The seats in the National Assembly were elected from single member districts, under the first-past-the-post voting system.
The following seats were up for election:

See also: Ilocos Norte's 2nd congressional district. The seat from Ilocos Norte's 2nd district was vacated when assemblyman-elect Julio Nalundasan was shot at his home in Batac just right after the 1935 legislative election. Nalundasan was murdered on September 20, 1935 while he was brushing his teeth. Ferdinand Marcos, the future president and son of Nalundasan's opponent Mariano, among others, was convicted of murder, but that was reversed on appeal years later.[2]
