The current Mayor of Athens is Haris Doukas, who took office on January 1, 2024 after defeating incumbent Kostas Bakoyannis in a runoff the previous October. The mayor is the chief executive of Greece’s capital, running city departments, preparing the municipal budget, signing public contracts, and representing Athens in court and in dealings with other levels of government.1Wikipedia. Haris Doukas
Who Haris Doukas Is
Doukas came to City Hall from the university, not from a long political career. He trained as a mechanical engineer at the Aristotle University of Thessaloniki and earned a doctorate focused on decision support systems for energy policy. Before running for office he was a professor at the National Technical University of Athens, working on energy and environmental policy.1Wikipedia. Haris Doukas
He launched his candidacy in August 2023 under the “Athens Now” banner, backed by PASOK–Movement for Change and Volt Greece, and campaigned on urban sustainability, climate action, and civic engagement. No candidate cleared the threshold needed to win outright in the first round, so Doukas and Bakoyannis went to a runoff. Doukas won with broad left-wing coalition support, ending Bakoyannis’s single term.1Wikipedia. Haris Doukas
Among his priorities, Athens participates in the EU Mission for 100 Climate-Neutral and Smart Cities by 2030, with projects including the DRYADS wildfire early-warning system and the Athens Energy Portal, a tool aimed at helping lower-income households cut energy costs and move toward renewables.
What the Mayor Actually Does
The mayor’s authority comes mainly from the Kallikratis Program (Law 3852/2010), which restructured Greek local government and defined the municipal executive. Later reforms, including Law 4555/2018, adjusted committee structures but left the core framework in place.
In day-to-day terms, the mayor runs the city. That means directing every municipal department, preparing and executing the annual budget, and signing off on public works contracts and municipal grants. The mayor is also the legal representative of the municipality in court, in contracts, and in official dealings with other authorities.
The mayor chairs the Executive Committee, which coordinates work across departments and reviews administrative proposals before they move forward. Strategic decisions passed by the full city council depend on the mayor’s office to translate them into policy on the ground. Every administrative act has to stay within the limits set by national law.
How Athens Elects Its Mayor
Athens holds municipal elections every four years. The most recent vote took place on the second Sunday of October 2023, and the next is expected in 2027.
A candidate wins outright in the first round by taking at least 43 percent of valid votes plus one. The winning list is then guaranteed a three-fifths supermajority of seats on the municipal council, so the new mayor can actually govern.2Groupe d’études géopolitiques. Regional and Local Elections in Greece, 8 October 2023
If nobody clears 43 percent, the top two candidates advance to a runoff the following Sunday, and whoever gets more votes wins. The local First Instance Court then certifies the results and handles any legal challenges. The mayor-elect is sworn in and officially begins work on the first day of the following January.
Who Can Run for Mayor
Greek law sets straightforward eligibility rules. A mayoral candidate must be a citizen of Greece or another EU member state, registered as an inhabitant of the municipality, eligible to vote, and at least 21 years old on election day. Candidates for ordinary council seats need only be 18.3Ministry of the Interior. Structure and Operation of Local and Regional Democracy
Some people are automatically disqualified: judges, religious officers, active military and security force personnel, and anyone with a financial debt to the municipality cannot stand for mayor, deputy mayor, or council member. Candidates also cannot run at both the municipal and regional level in the same cycle; if someone is somehow elected to both, both elections are voided. Party lists must meet a gender balance rule, with at least 40 percent of nominees of each gender, or the list is rejected.3Ministry of the Interior.

Candidacies are filed through a digital portal run by the Ministry of the Interior, with identification details and the candidate’s party list affiliation.
Who Keeps the Mayor in Check
The mayor does not have a free hand. The Hellenic Court of Audit, Greece’s supreme audit institution, has constitutional authority under Article 98 of the 1975 Constitution to audit expenditures and monitor the revenue of local government, including the Municipality of Athens.
Large municipal contracts face a mandatory legality review before they can be signed. Under a 2023 reform (Law 5016/2023), contracts for public works, supplies, or services above €1.7 million (excluding VAT) require a full legality audit by the Court’s judicial sections, while contracts between €300,000 and €1.7 million go through a legality check by the Court’s regional commissioners.4Scientific Research Publishing.

A mayor who mismanages public funds can face personal civil liability proceedings before the Court of Audit. The Decentralized Administration of Attica, headed by a centrally appointed secretary-general, also supervises municipal decisions to make sure they comply with national law.
Recent Mayors
The office has changed hands across the political spectrum in recent cycles. Kostas Bakoyannis, a center-right politician from one of Greece’s most prominent political families, served from 2019 to 2023 before losing to Doukas.5Harvard Kennedy School Institute of Politics. Kostas Bakoyannis Before Bakoyannis, Giorgos Kaminis held the office after defeating conservative incumbent Nikitas Kaklamanis in a close runoff. Athens’s mayoralty has long attracted candidates from across the political landscape, reflecting the city’s role as the symbolic and administrative center of Greek public life.
