The Gjemnessund Bridge ({{langx|no|Gjemnessundbrua}}) is a suspension bridge that crosses the Gjemnessundet strait between the mainland and the island of Bergsøya in Gjemnes Municipality in Møre og Romsdal county, Norway. The {{convert|1257|m|ft|adj=mid|-long}} bridge was the longest suspension bridge in Norway until the opening of the Hardanger Bridge in 2013, although it did not have the longest span ({{convert|623|m|disp=or}}), being eclipsed by the Askøy Bridge.

Many bridges slowly deteriorate and need to be repaired because the salty seawater damages the concrete and the iron inside it. The Gjemnessund Bridge has had a problem with seabirds, whose manure contain salt and ammonia. The salt and ammonia damages the concrete. To prevent this, the bridge is cleaned, and the critical parts of the concrete are covered with an elastic membrane that protects the concrete against the manure and the harmful content.{{Cite news |last=Bjørshol |first=Øivin |date=15 March 2004 |title=Krykkjeskit skader Gjemnessundbrua |url=http://www.tk.no/nyheter/article908606.ece |access-date=2008-11-13 |work=Tidens Krav |language=Norwegian}}
