The Geiranger fjord is a fjord in the Sunnmøre region of Møre og Romsdal county in Norway. It is in the municipality of Stranda. It is a 15-kilometre (9.3 mi) long branch of the Storfjord (Great Fjord).
The fjord is one of Norway's most visited tourist sites and has been listed as a UNESCO World Heritage Site, jointly with Nærøyfjord, since 2005, although this status is now threatened by the disputed plans to build power lines across the fjord. A car ferry, which doubles as a sightseeing trip, is operated by Fjord1 Nordvestlandske. It runs lengthwise along the fjord between the small towns of Geiranger and Hellesylt. The fjord is also host to several impressive waterfalls.
