The Mayor of Bath is a ceremonial post held by a member of the charter trustees of Bath, elected annually by the trustees of the city.

In 1189, Richard I of England granted a charter to the city of Bath establishing a mayor, with the first recorded mayor being John de Porta in 1230.

In 1590 a Royal Charter of Incorporation was issued confirming the city's status of a corporate body of Mayor, Alderman and Citizens.

When local government was restructured through the Local Government Act 1972, Bath was restructed as a district council within the County of Avon.

Until further local government re-organisation in 1996, the role of mayor was held by the chairman of Bath City Council, since the creation of Bath and North East Somerset Council the role has been held by the chairman of the Charter Trustees of the City of Bath.
