The Mayor of Kansas City, Missouri is the highest official in the Kansas City, Missouri Municipal Government. Since the 1920s the city has had a council-manager government in which a city manager runs most of the day-to-day operations of the city. Unlike most cities of its size, by charter Kansas City has a "weak-mayor" system, in which most of the power is formally vested in the city council. However, the mayor is very influential in drafting and guiding public policy. The mayor presides over all city council meetings and has a casting vote on the council. Due to these combined factors the mayor, in fact, holds a significant amount of de facto power in the city government.
