The Governor of Arizona is the head of government and head of state of the U.S. state of Arizona.[4] As the top elected official, the governor is the head of the executive branch of the Arizona state government and is charged with faithfully executing state laws.[4] The governor has the power to either approve or veto bills passed by the Arizona State Legislature[5]; to convene the legislature[4]; and to grant pardons[6], except in cases of impeachment. The governor is also the commander-in-chief of the state's military forces.[7]

Twenty-two people have served as governor over 26 distinct terms. All of the repeat governors were in the state's earliest years, when George W. P. Hunt and Thomas Edward Campbell alternated as governor for 17 years and, after a two-year gap, Hunt served another term. One governor, Evan Mecham, was successfully impeached, and one, Fife Symington, resigned upon being convicted of a felony. The longest-serving governor was Hunt, who was elected seven times and served just under fourteen years. The longest single stint was that of Bruce Babbitt, who was elected to two four-year terms after succeeding to the office following the death of his predecessor, Wesley Bolin, serving nearly nine years total. Bolin had the shortest tenure, dying less than five months after succeeding as governor. Four governors were actually born in Arizona: Campbell, Sidney Preston Osborn, Rose Mofford, and Babbitt. Arizona has had four female governors, the most in the United States, and was the first—and until 2019 (when Michelle Lujan Grisham succeeded Susana Martinez in neighboring New Mexico) the only—state where female governors have served consecutively. Because of a string of deaths in office, resignations, and an impeachment, Arizona has not had a governor whose complete term of service both began and ended because of "normal" election circumstances since Jack Williams was in office, from 1967 to 1975.

The current Governor is Republican Doug Ducey, who took office on January 5, 2015.
