The Geiranger Fjord (Norwegian: Geirangerfjorden) is a fjord in the Sunnmøre region of Møre og Romsdal county, Norway. It is located entirely in the Stranda Municipality. It is a 15-kilometre-long (9+1⁄2 mi) branch off the Sunnylvsfjorden, which is a branch off the Storfjorden (Great Fjord). The small village of Geiranger is located at the end of the fjord where the Geirangelva river empties into it.

The fjord is one of Norway's most visited tourist sites. In 2005, it was listed as a UNESCO World Heritage Site, jointly with the Nærøyfjorden. This status was challenged 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 scheduled to require zero-emissions ships in 2026.
