The Cvetković–Maček Agreement, also known simply as the Sporazum in English-language histories, was a political compromise on internal divisions in the Kingdom of Yugoslavia. It was settled on August 26, 1939, by Yugoslav prime minister Dragiša Cvetković and by Vladko Maček, a Croat politician. The agreement established the Banovina of Croatia, with boundaries drawn to include as many ethnic Croats as possible. This effectively created within unitary Yugoslavia an autonomous Croatian sub-state, a demand of Croat politicians since the 1918 founding of the Kingdom of Serbs, Croats and Slovenes (Yugoslavia). The Banovina later provided a model for eventual post-war constitutional arrangements in Federal Yugoslavia (1943–1945).

Vladimir Maček was a politician in the Kingdom of Yugoslavia. As a leader of the Croatian Peasant Party (HSS) following the 1928 assassination of Stjepan Radić, Maček had been a leading Croatian political figure until the Axis invasion of Yugoslavia in 1941. As a leader of the HSS, Maček played a key role in establishment of the Banovina of Croatia, an autonomous banovina in Yugoslavia in 1939.
