Sidney Preston Osborn was an American politician who was the first secretary of state of Arizona, and later the seventh governor of Arizona and is, as of 2024, the only governor of Arizona to be elected to four consecutive terms. Osborn is also the second native-born governor of Arizona, preceded by Thomas Edward Campbell.

The secretary of state of Arizona is an elected position in the U.S. state of Arizona. Since Arizona does not have a lieutenant governor, the secretary stands first in the line of succession to the governorship. The secretary also serves as acting governor whenever the governor is incapacitated or out of state. The secretary is the keeper of the Seal of Arizona and administers oaths of office. The current office holder is Democrat Adrian Fontes.
