Tomari Ōhashi Bridge, Steel plate bridge in Naha, Japan.

The Tomari Ōhashi Bridge is a 1,118-metre bridge over Naha Port's Tomari wharf, linking Wakasa and Akebono in Naha, Okinawa. It opened in 1986 as part of the Naha Port Road connecting the Naha and Shinminato wharves. Its ends have steep gradients to keep clear of vessels on the Tomari wharf regular route.

The bridge opened in 1986 as a major step forward for Naha, creating a direct link between the port area and the rest of the city. This connection changed how people moved between districts and supported the city's development.

The bridge crosses the mouth of Tomari Port, the harbour whose regular ferry and shipping routes the span was built high enough not to obstruct. Its Japanese name, Tomari Ōhashi, simply means "Tomari Great Bridge", pairing the port district's name with the word for a large bridge.

The bridge has steep gradients at both ends, so the climb is sharp; crossings are closed when wind speeds reach roughly 20 m/s. It links Wakasa in Naha with Akebono over Tomari Port, and since the early 2010s an interchange on the Naha West Road at the Wakasa end gives direct access toward Naha Airport.

When it opened on 11 April 1986, the 1,118 m Tomari Ōhashi was the longest bridge in Okinawa Prefecture, surpassing the 762 m Sesoko Bridge in Motobu. It has since dropped to fifth place among the prefecture's bridges, behind the Irabu, Kouri, Kurima, Ikema and Hamahiga bridges.
