The United States District Court for the Southern District of Ohio (in case citations, S.D. Ohio) is one of two United States district courts in Ohio and includes forty-eight of the state's eighty-eight counties–everything from the Columbus area southward. Appeals from the court are taken to the United States Court of Appeals for the Sixth Circuit at Cincinnati (except for patent claims and claims against the U.S. government under the Tucker Act, which are appealed to the Federal Circuit).
