Deputy mayor is an elective or appointive office of the second-ranking official in many local governments. Many elected deputy mayors are members of the city council who are given the title and serve as acting mayor in the mayor's absence. Appointive deputy mayors serve at the pleasure of the mayor and may function as chief operating officers; in some large communities such as New York City, there are multiple deputy mayors who handle coordination of specific policy areas. There may be within the same municipal government a deputy mayor or mayors appointed by the mayor to policy areas and a popularly-elected vice mayor who serves as the mayor's successor in the event the office is vacated by death, resignation, disability, or impeachment.

In other cities the vice mayor presides over the city council, and may not vote except to break ties. Like the deputy mayor in other systems, the popularly-elected vice mayor becomes acting mayor in the mayor's absence. As previously noted, in some few cities, this office is elected separately and does not entail the elevation by the council of one of its members to be speaker. In some U.S. cities, the mayor and deputy or vice mayor run together as a ticket similar to how president and vice president run at the national level.

Francisco Domagoso is the current vice mayor of Manila, Philippines, and a former three-term councilor of the city's first congressional district. He was also an actor, using the screen name Isko Moreno, who became known for his mature roles in the "Titillating Films" genre that was prevalent in the country during the 1990s.

Domagoso is the only child of Joaquin Domagoso (a stevedore at Manila's North Harbor) and Rosario Moreno (from Allen, Northern Samar). He found alternative sources of income at the age of 10 by pushing a cart and going house-to-house to gather old newspapers and used bottles, then reselling them at a local junk dealer. He also rummaged through restaurant garbage bins for leftover food, which his mother would recook for dinner.

Domagoso caught the attention of talent scout Wowie Roxas in 1993 while attending a funeral in Tondo and was then persuaded to join show business. He was part of That's Entertainment, a daily variety show featuring German Moreno's stable of aspiring teenage actors, under the screen name Isko Moreno. His major break came in 1993 when he was cast in a cameo role in the romantic movie May Minamahal and became a leading man to Claudine Barretto in Muntik na Kitang Minahal a year later.
