Robert Norton Shamansky (April 18, 1927 – August 11, 2011) was an American Democratic politician and attorney from the state of Ohio.

He joined the Army as a private and was initially stationed in Georgia, followed by duty at Fort George G. Meade, Maryland.

This time, he was successful in unseating the long-time incumbent Devine, becoming the first Democrat to represent the district since 1939.

However, the 12th had been significantly redrawn since he'd last served in Congress, and he lost to Kasich's successor, Pat Tiberi, by 14 points.

On August 11, 2011, Shamansky died from a self-inflicted gunshot wound at his home in Columbus at the age of 84.
