Mersin Metropolitan Municipality City Council (Mersin Büyükşehir Belediye Meclisi) is the principal legislative and decision-making body of the Mersin Metropolitan Municipality, operating under Turkey’s Metropolitan Municipality Law No. 5216, which defines municipal councils as the core organs responsible for adopting strategic plans, approving budgets, setting annual targets, enacting regulations, and making key policy decisions for the metropolitan area; the council is composed of elected councilors chosen in local elections held every five years, with the Metropolitan Mayor serving as the natural member and chair, presiding over meetings, while decisions are generally taken by majority vote during regular (usually monthly) sessions, supported by specialized committees (ihtisas komisyonları) such as budget, planning, environment, transportation, and equality committees that examine issues in detail and submit reports to the full council, thereby structuring democratic local governance and ensuring municipal services and policies align with legal frameworks and public needs.
