Kelly Arthur Anthon (born August 4, 1974) is a Republican Idaho State Senator since 2015 representing District 27.
He served as a missionary for the Church of Jesus Christ of Latter-day Saints in Japan, and later graduated from Brigham Young University with a Bachelor of Arts in anthropology in 1998 and from the University of Idaho College of Law in 2002 where he was also named the Bistline Scholar and student body president.
Anthon also serves on the corporate board of directors of the Mart Group—a potato processing and marketing company.
When incumbent Senator Dean Cameron resigned his seat for an appointment as the director of the Department of Insurance, the Legislative District 27 Republican Central Committee sent three names in order of preference to Governor Butch Otter: Anthon, Doug Pickett of Oakley, and Wayne Hurst of Declo.
In 2024, Anthon was elected to the Idaho Senate's top role of President Pro Tempore.
