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.

The Great Seal of the State of Arizona is the state seal of the U.S. state of Arizona as designated in the state consitution. Article 22, Section 20 of the State of Arizona Constitution by the Arizona State Legislature details the design and usage of the seal.
