Greek Prime Minister Kyriakos Mitsotakis nominated parliament speaker Constantine Tassoulas from his centre-right New Democracy party for the Greek presidency.
Other prominent figures, including Bank of Greece Governor Yannis Stournaras and former prime ministers Lucas Papademos and Evangelos Venizelos, had also been considered.
Tassoulas, a lawyer, served as Culture Minister a decade ago and accompanied Mrs Clooney to the Acropolis Museum during her visit to Athens as the international awareness of the campaign received a boost with the support of both Mr and Mrs Clooney.
The Greek presidency is largely ceremonial, with the president elected to a five-year term by the country’s 300 lawmakers through a process that may require up to five rounds of voting. Victory in the first or second round requires 200 votes, decreasing to 180 in the third round and a simple parliamentary majority of 151 in the fourth.
The New Democracy party currently holds 156 seats, with the centre-left PASOK controlling 31 and the left-wing SYRIZA holding 26.
The first round of voting is scheduled for 25 January with opposition parties not expected to support Tassoulas' candidacy. A fourth-round vote requiring a simple majority is anticipated by 12 February.
President of Hellenic Republic, Katerina Sakellaropoulou, was the country's first female president and her five-year term expires in March.
