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.
