Trey Grayson (born April 18, 1972 in Kenton County, Kentucky) is the Secretary of State for the state of Kentucky. He is a member of the Republican Party. Prior to being elected Secretaty of State, Grayson was an attorney in private practice.

After graduating from Dixie Heights High School in Fort Mitchell, Kentucky, Grayson went to Harvard University, where he graduated with honors in 1994 with an A.B. in government. He then returned to Kentucky, entering a J.D./M.B.A. dual-degree program at the University of Kentucky, where he was one of the first Kentucky MBA scholars and one of the first two Bert T. Combs Scholars, the College of Law’s top scholarship. After earning both degrees in 1998, he was an attorney with Greenebaum Doll & McDonald and later Keating, Muething & Klekamp, where he focused on estate planning and corporate law.

Grayson stamped himself as one of the Kentucky Republicans' future stars in 2007. In an election that saw Republican Governor Ernie Fletcher lose by a 17% margin, Grayson scored a 14-point win in his bid for reelection as Secretary of State. He and incumbent Commissioner of Agriculture Richie Farmer, who won his race by a nearly 2-to-1 margin, became the first Kentucky Republicans to win statewide office in an election won by a Democratic gubernatorial candidate since 1915.
