Ioannis Alevras (Greek: Ιωάννης Αλευράς; 1912 – 6 April 1995[1]), sometimes spelled Yannis Alevras, was a Greek Panhellenic Socialist Movement politician and Speaker of the Hellenic Parliament, who served as acting President of Greece in March 1985.

He was a prominent syndicalist and a key figure in the foundation of OTOE (Federation of Bank Employee Organizations of Greece) in 1955.

Alevras defended fellow Center Union MP Andreas Papandreou, son of George, during his trial for the Aspida scandal.

The Aspida Group allegedly comprised officers of the Hellenic Army, who belonged to the centre or the left and wanted to assume control of an army dominated at the time by right-wing officers who had fought in the Greek Civil War against the left.

He joined the Panhellenic Socialist Movement (PASOK), a new Party under Andreas Papandreou, and achieved re-election in 1974 Greek legislative election.

Andreas Papandreou became Prime Minister while Alevras was elected Speaker of the Greek Parliament.

In the same year, Papandreou was indicted by Parliament in connection with the US$200 million Bank of Crete embezzlement Koskotas scandal.

He was accused of helping the embezzlement by ordering state corporations to transfer their holdings to the Bank of Crete where the interest was allegedly skimmed off to benefit PASOK.

The new government included representatives of New Democracy, PASOK and Synaspismos and organized the 1990 Greek legislative election.

The heightened public irritation over the Macedonia issue with the neighbouring Republic of Macedonia caused several ND parliament members, led by Antonis Samaras, to withdraw their support from Mitsotakis' government and form a new political party, Political Spring (Politiki Anoiksi).
