William F. Turner (1816 – December 23, 1899) was the first Chief Justice of the Territory of Arizona, serving in that capacity for about seven years. Born in Pennsylvania, he attended college in Ohio and practiced law there after graduation. When the Arizona territory was created, he sought to be appointed its first governor but was instead made Chief Justice of the Territorial Supreme Court of Arizona. Renominated to a second four-year term, he was later removed under a cloud of scandal and political opposition while having an unblemished legal record. Turner then formed a successful law practice in Kansas, but his final years were impoverished.
