Dennis John Kucinich (pronounced /kuːˈsɪnɪtʃ/; born October 8, 1946) is a Democratic member of the United States House of Representatives and was a candidate for the Democratic nomination for President of the United States in the 2004 and 2008 elections.

Kucinich currently represents the 10th District of Ohio in the House of Representatives, which he has been serving since 1996. His district includes most of western Cleveland as well as suburbs such as Parma and Lakewood. He is currently the chairman of the Domestic Policy Subcommittee of the House Committee on Oversight and Government Reform. He is also a member of the Education and Labor Committee.

From 1977 to 1979, Kucinich served as the 53rd mayor of Cleveland, Ohio, a tumultuous term in which he survived a recall election and was successful in a battle against selling the municipal electric utility before being defeated for reelection by George Voinovich.
