Ante Marković (25 November 1924 – 28 November 2011) was a Croatian and Yugoslav politician, businessman and engineer. He is most notable for having served as the last Prime Minister of Yugoslavia from 1989 to 1991.

Marković, was a Bosnian Croat, born in Konjic, then a part of the Kingdom of Serbs, Croats, and Slovenes, presently in Bosnia and Herzegovina to a poor peasant family. In 1943 he joined the Communist Party of Yugoslavia and fought with the Yugoslav Partisans in World War II. He received a degree in electrical engineering from the Electrotechnical Department of the Technical Faculty of the University of Zagreb in 1954. He remained in Zagreb, where he was a director of Rade Končar Industrial Works from 1961 to 1984.

In 1986, he became president of the Presidency of Socialist Republic of Croatia replacing Ema Derossi-Bjelajac. He held that position until 1988, when he was replaced by Ivo Latin.

He became prime minister in March 1989 following the resignation of Branko Mikulić. After that decision had become public, the U.S. had anticipated cooperation because Marković was known "to favor market-oriented reforms" – the BBC declared that he is "Washington's best ally in Yugoslavia". At the end of the year, Marković launched a new and ambitious program of unprecedented economic reforms, including the establishment of a fixed exchange rate, the privatization of failing social enterprises, as well as a program of trade liberalization. The result of his economic reforms was a halt to inflation, leading to a rise in Yugoslavia's standard of living. Nonetheless, the short-term effect of economic reforms undertaken by Marković led to a decline in Yugoslavia's industrial sector. Numerous bankruptcies occurred as socially-owned enterprises struggled to compete in a more free market environment, a fact later wielded against Marković by many of his opponents. By 1990, the annual rate of growth in GDP had declined to −7.5%.

Marković was the most popular politician in Yugoslavia and owed his popularity to his image of a modern Western-styled politician. He had become a leading political figure for those who wanted Yugoslavia to be transformed into a modern, democratic federation. Marković also maintained popularity by staying out of increasingly virulent quarrels within the leadership of the League of Communists of Yugoslavia or trying to act as mediator between various republics.

When the League of Communists of Yugoslavia broke up in January 1990, Marković had only his popularity and the apparent success of his economic program on his side. In July 1990, he formed the Union of Reform Forces of Yugoslavia (Savez reformskih snaga), a political party supporting a more centralized Yugoslav Federation, and accession to the European Community.

This decision was not well received. Borisav Jović, then the President of the Presidency of Yugoslavia, commented

The general conclusion is that Ante Markovic is no longer acceptable or reliable to us. No one has any doubts in their mind any longer that he's the extended arm of the United States in terms of overthrowing anyone who ever thinks of socialism, and it is through our votes that we appointed him Prime Minister in the Assembly. He is playing the most dangerous game of treason.
