The 20th Legislative Assembly of Quebec was a pivotal session in the province's political history, spanning from 1936 to 1939. It followed a decisive general election that reshaped the governance of Quebec and introduced a new era of conservative nationalism under Maurice Duplessis.

This assembly marked a turning point, as the Union Nationale unseated the long-ruling Liberal Party. The shift reflected growing public concern over economic conditions during the Great Depression and dissatisfaction with the incumbent government.

The functioning of the 20th Legislative Assembly followed the standard parliamentary procedures of Quebec’s National Assembly, with the governing party setting legislative priorities and the opposition providing scrutiny.
