The 2006 Ohio State Treasurer election was held on November 7, 2006. The Democratic nominee, Franklin County Treasurer Richard Cordray, defeated Republican challenger Ashtabula County Auditor Sandra O'Brien by a wide margin of 15 points. Cordray would not serve out a full term as treasurer, as he would go on to resign in 2009 in order to take office after winning the 2008 Ohio Attorney General special election held following Marc Dann's resignation.

As of 2025, this is the last time Democrats have won the office of Ohio State Treasurer.

Background Following Joe Deters' victory in the 2002 Ohio State Treasurer election, he went on to resign in 2004 after winning election to the office of Hamilton County Prosecutor. To fill the vacancy, Governor Bob Taft appointed Lieutenant Governor Jennette Bradley to the office.

Campaign The Republican primary was held on May 2, 2006. The incumbent State Treasurer Jennette Bradley faced a primary challenge from Ashtabula County Auditor Sandra O'Brien. Bradley ran a lax campaign, with her advisors telling her to save her funds until the election. O'Brien attacked Bradley for her more left-leaning views, such as being pro-choice, and positioned herself as the more conservative candidate. In the end, O'Brien won an upset victory over Bradley, narrowly defeating her by three points.
