1985 Greek parliamentary election

Parliamentary elections were held in Greece on 2 June 1985. The governing political party, PASOK of Andreas Papandreou, was re-elected, defeating the liberal conservativeNew Democracy party of Konstantinos Mitsotakis.

The election campaign was dominated by the ongoing constitutional crisis initiated by Papandreou in March 1985 to advance his preferred candidate, Christos Sartzetakis, for the president of Greece. At the same time, he proposed constitutional revisions to remove the presidential powers that were acting as checks and balances on Papandreou's position. The presidential vote took place amid intense political tension and accusations of constitutional violations, ending with Sartzetakis becoming president. Mitsotakis, as leader of the opposition, denounced the presidential election as illegal and vowed to remove Sartzetakis if his party won, deepening the constitutional crisis.

The confrontation at the presidential election carried over to the parliamentary election campaigns, which polarized Greek society. On one side, Papandreou invoked memories of the Greek Civil War (1946–1949) and Junta (1967–1974), associating New Democracy with the authoritarian Right of the past, while on the other side, Mitsotakis warned the public of Papandreou's totalitarian designs. However, Sartzetakis' election ultimately benefited Papandreou and his party, securing victory in the general elections by consolidating support from the Left, even as they lost ground in the Center amid Greece's worsening economy under his leadership.

After the election, all political parties accepted Sartzetakis as president, ending the constitutional crisis, despite a later court ruling designating the election of Sartzetakis as unconstitutional. The constitutional amendments that came into effect in 1986 substantially strengthened Papandreou's executive authority. However, the monopoly of power and dominance of Papandreou caused strategic reevaluation and alignment in the New Democracy and communist parties, Communist Party of Greece (KKE) and KKE-Interior, leading to Papandreou losing the premiership in 1989.
