Mayor

A mayor was the political leader of a planetary settlement. The position was equal to the Romulan term maiori. Its Bajoran counterpart was the tetrarch. The term mayor was also used on Earth. 

History
In 2024, the mayor of the Earth city San Francisco was the Honorable Helen Burke. 

In 2367, Marie Picard told Jean-Luc Picard that the mayor of La Barre, Earth wanted to give him a parade to honor Jean-Luc's first return to his hometown in twenty years. 

By 2380, Henri Bonnaire had been La Barre's mayor for most of Jean-Luc Picard's adult life. Mayor Bonnaire presided of the wedding of Beverly Crusher and Captain Picard, which was unusual for a mayor in France but acceptable because La Barre was small and Bonnaire and Picard knew each other since childhood. 

Since 2409 (year 2013 in local timekeeping), Mayor Truffles was the leader of Gingerbread Colony.
