Ekstremsportveko (Extreme Sports Week), or "Veko" as it is commonly called by the locals, is a festival held annually in Voss, Norway. Established in 1998 by Einar Raa Nilsen, Frode Solbakk, Oyvind Kindem and Even Rokne, has grown to become one of the world's largest extreme sports festivals.

The week contains national and international competitions in disciplines as BASE jumping, parachuting, paragliding, hanggliding, kitesurfing, climbing, longboarding, mountainbike, BMX, rafting, whitewater kayaking, big air and Multisport.

In 2007 more than 1000 competitors and more than 40,000 spectators attended the event. The festival was covered by more than 250 reporters from both the Norwegian media as well as the international media. "Veko" does not employ many people as they base the organizing and execution of the event mostly on volunteers. In 2007 more than 600 volunteers assisted in getting the festival running smoothly. In 2007 "Veko" received two rewards. One reward was "Best sponsor object of the year". The Norwegian Sponsor and Event association gave the prize to Ekstremsportveko stating; “Ekstremsportveko has moved away from a focus on commercialism to pure focus on their own identity where the sponsors have a more intimate presence than what was the case earlier when the activity was mentioned by the name of the sponsor”. The second was "The tourism prize of the year". Innovation Norway states “With this prize we wish to focus on the overall experience in the tourism industry. Ekstremsportveko is definitely a worthy winner, says the director of tourism, Per-Arne Tuftin from Innovation Norway.
