The Arizona Supreme Court is the state supreme court of the U.S. state of Arizona. Sitting in the Supreme Court building in downtown Phoenix, the court consists of a chief justice, a vice chief justice, and five associate justices. Each justice is appointed by the governor of Arizona from a list recommended by a bipartisan commission. Justices stand for retention in an election two years after their appointment and then every six years. They must retire at age 70.

Alfred Morrison Franklin was an American jurist and politician. He was the first chief justice of the Arizona Supreme Court and served as a member of Arizona's 1910 constitutional convention.
