Bill Ketron, Jr., born on September 4, 1953, is an American politician from Tennessee who served as a Republican member of the Tennessee Senate representing the 13th district (Lincoln, Marshall, and Maury counties, and parts of Rutherford County) from 2003 until his resignation in 2018. During his Senate tenure, he was a prominent conservative figure who sponsored anti-Sharia legislation aimed at prohibiting the application of foreign legal systems in Tennessee courts, focusing on national security issues. These efforts positioned him as a vocal advocate against perceived threats from Islamic law, drawing both conservative support and criticism from civil liberties groups. In 2018, he transitioned to executive office by winning the Rutherford County mayoral election, assuming the role on September 1 after resigning from the legislature. As mayor, he focused on local governance including economic development, infrastructure, and public safety. His reelection bid in 2022 was unsuccessful, losing the Republican primary to former state representative Joe Carr. His career reflects broader trends in Southern Republican politics with emphasis on cultural conservatism and national security.
