Tsuneo Watanabe (渡邉 恒雄 Watanabe Tsuneo?, born May 30, 1926) is a Japanese businessman. He leads the Yomiuri Shimbun.
When the Japan Professional Soccer League was established, he insisted that each football club should put each company's name on the football clubs. Usually, in Europe and the United States, each professional team or club put each city's name on the team. In August 2004, Watanabe resigned as Yomiuri Giants president after it was revealed that the Giants baseball club had violated scouting rules by paying ¥2 million to pitching prospect Yasuhiro Ichiba. Ten months later, Watanabe was hired as chairman of the Yomiuri Giants.
