Legislative elections were held in Greece on Sunday 25 January 2015 to elect all 300 members of the Hellenic Parliament in accordance with the constitution. The election was held earlier than scheduled due to the failure of the Greek parliament to elect a new president on 29 December 2014.

Indirect presidential elections were held in Greece in December 2014 and February 2015 for the succession to Karolos Papoulias as President of the Hellenic Republic. The candidate of the ND–PASOK government, Stavros Dimas, failed to secure the required majority of MPs of the Hellenic Parliament in the first three rounds of voting in December. According to the provisions of the Constitution of Greece, a snap election was held on 25 January 2015, which was won by the left-wing Syriza party. Following the convening of the new Parliament, the presidential election resumed. On 18 February 2015, veteran ND politician Prokopis Pavlopoulos, backed by the Syriza-ANEL coalition government, was elected with 233 votes.
