The Ken-O Expressway (圏央道, Ken-Ō Dō), or Metropolitan Inter-City Expressway (首都圏中央連絡自動車道, Shuto-ken Chūō Renraku Jidōsha-dō), is a partially completed ticket system toll expressway in Japan, owned and operated by the Central Nippon Expressway Company and East Nippon Expressway Company. In conjunction with the Tokyo Bay Aqua-Line and the Bayshore Route of the Shuto Expressway, it will form a full outer ring road of Tokyo. It is assigned the national highway Route 468 number.

Portions of the existing Yokohama-Yokosuka Expressway, Shin-Shōnan Bypass and Chiba-Tōgane Road and the planned Yokohama Ring Expressway will be incorporated into the road.

The section owned by the Central Nippon Expressway Company runs from the east end of the Shin-Shōnan Bypass west along the bypass and north to interchange 42. The rest is owned by the East Nippon Expressway Company.
