The Mayor is a constitutional position in each of the five City Corporations constituted under the Greater Bengaluru Authority within the city of Bengaluru (Greater Bengaluru Area). Under the Greater Bengaluru Governance Act, 2024 (Karnataka Act No. 36 of 2025), which came into force on 15 May 2025, the former Bruhat Bengaluru Mahanagara Palike (BBMP) was dissolved and replaced by a three-tier governance structure. As of 2 September 2025, when the new structure became fully operational, Bengaluru is administered by five City Corporations:

Each Corporation is headed by its own elected Mayor and an appointed Commissioner. There is no longer a single Mayor for Bengaluru. Instead, each of the five Mayors serves their respective City Corporation and is an ex-officio member of the Greater Bengaluru Authority (GBA), the apex coordinating body chaired by the Chief Minister of Karnataka. The role of Mayor is largely ceremonial. The Mayor also plays a functional role in deliberating over discussions in their respective City Corporation. The term of each Mayor is set for 30 months as per the Greater Bengaluru Governance Act, 2024.

Previously, under the Bruhat Bengaluru Mahanagara Palike Act, 2020, Bengaluru had a single Mayor for the entire city with a five-year term, which was never implemented as no council was elected after the enactment of this law, which was eventually replaced with Greater Bengaluru Governance Act, 2024. Under the earlier Karnataka Municipal Corporations Act, 1976, the term of the Mayor was fixed at one year.
