Kvalsaukan Bridge (Norwegian: Kvalsaukan bru) is a bridge that crosses the Hognfjorden in the municipality of Sortland in Nordland county, Norway. It is part of the road between Sortland and Andøy. The bridge is 425 metres (1,394 ft) long and the maximum clearance to the sea is 8 metres (26 ft).

Kvalsaukan Bridge was opened in 1975. It was one of four bridges that were built in the 1970s to connect the islands of Vesterålen to each other. The other bridges that were built during that period are Sortland Bridge, Andøy Bridge, and Hadsel Bridge. Together with Tjeldsund Bridge near Harstad these bridges connect the islands of Vesterålen to the mainland. Kvalsaukan Bridge is the only of these four bridges that was never a toll bridge.
