Legislative elections were held in Greece on 7 July 2019. The elections were called by Prime Minister Alexis Tsipras on 26 May 2019 after the ruling Syriza party lost the European and local elections. They were the first national elections since the voting age was lowered to 17, and the number of parliamentary constituencies was increased from 56 to 59. Athens B, the largest constituency before the 2018 reforms, with 44 seats, was broken up into smaller constituencies, the largest of which had 18 seats.

European Parliament elections were held in Greece on 26 May 2019 to elect the 21 Greek members of the European Parliament. The elections were held alongside the first round of the local and regional government elections, resulting in a major defeat for the governing Syriza party, and leading to Prime Minister Alexis Tsipras bringing forward the scheduled parliamentary elections for 7 July 2019.
