The Akinada Bridge (安芸灘大橋, Akinada Ō-hashi) is a suspension bridge in Kure, Hiroshima, Japan that crosses the Seto Inland Sea. Completed in 1999, it has a main span of 750 m (2,460 ft). The first and largest bridge on the Akinada Tobishima Kaido, it was constructed by Penta-Ocean Construction, at a cost of 50 billion yen.

The bridge was opened to traffic on 18 January 2000. The bridge is part of Hiroshima Prefecture Route 74, a route that begins in Honshu and crosses over the Seto Inland Sea via the Akinada Bridge to Shimo-kamagari Island to the south. The bridge is tolled and operated by the Hiroshima Prefecture Road Corporation. It is the longest bridge in Japan to be maintained by a prefecture. The average daily traffic volume on the bridge was 4,000 vehicles by May 2000, far exceeding the expected volume of 2,400 vehicles using it every day.
