NSB Class 71 (Norwegian: type 71) is an electric multiple unit used by Flytoget for the Airport Express Trains on the Gardermoen Line of Norway. Sixteen three-car train sets were built by Adtranz Strømmen between 1997 and 1998. The units are capable of 210 km/h (130 mph), connecting Oslo Central Station and other stations in Metropolitan Oslo to the Oslo Airport, Gardermoen, along Norway's only high-speed railway.

In a three-car configuration, the units weigh 158 tonnes (156 long tons; 174 short tons) and are 82.3 metres (270 ft 0 in) long, with a power output of 2,645 kW (3,547 hp). The units are similar to the NSB Class 73, and are related to the Swedish X2 units. By 2009, all units were expanded with a fourth car.
