Frank Carroll is an American politician and a Republican member of the Arizona Senate representing District 28 since January 9, 2023.

Along with fellow Republican David Livingston, he is a member of the National Association of Christian Lawmakers, an organization founded by Jason Rapert in 2019 that opposes same-sex marriage and supports anti-abortion legislation.

[12] In 2019, Carroll was part of a bipartisan group of Arizona lawmakers who, following a deadly flood, supported the appropriation of $20 million to build a bridge over Tonto Creek at a site known as the Bar X crossing.

His proposal (Senate Bill 1566) was criticized by the Arizona Association of Counties, which noted that it would violate the National Voter Registration Act.

[19] In 2022 and 2023, Carroll introduced legislation to bar the State of Arizona from contracting with any business that "discriminates" against firearm manufacturers or the National Rifle Association of America.

Carroll introduced the bill, based on a nearly identical measure enacted in Texas, that targeted banks that declined to take gun manufacturers on as clients following shooting massacres.
