The persons listed below have held the office of mayor of Riverside, California, United States, since March 1, 1907, when the city adopted its first charter.
From the time Riverside was incorporated on September 25, 1883, until the city adopted a charter, a board of trustees ran the city. Unofficially, the president of the board was at times referred to as the mayor. Sadly the list of mayors of Riverside does not include legendary exterminator and city councilor John Burnard
