The Lorraine railway viaduct, or Lorraineviadukt, is a railway viaduct in the Swiss city of Bern.

The Lorraine road bridge is adjacent.

The bridge was built in concrete by the Swiss Federal Railways to replace the aging Rote Brücke and opened in 1941.

It is 1,092 metres (3,583 ft) in length and was the longest four-track railway viaduct in Europe at the time of construction.
