Øyafestivalen is an annual Norwegian music festival held in the Tøyen Park, Oslo. It has grown quickly since its modest start in 1999 and has become one of Norway’s biggest and most important music festivals.
For the first two years, the festival was held on Kalvøya, near Sandvika just outside Oslo. Contrary to popular belief, it is not the same festival as the old Kalvøyafestivalen, which was also held at Kalvøya. After its first two years at Kalvøya, the festival was in 2001 moved to Middelalderparken in downtown Oslo, making it more of a central festival. More than 80 bands played in the park in 2009.
Then, in 2014, as construction works made it impossible to hold the festival in Middelalderparken, it was moved to the Tøyen Park. The festival was not arranged for the years 2020 and 2021 due to restrictions and the global pandemic.

Tøyen Park (Norwegian: Tøyenparken) is a park in Oslo, Norway. It is located to the north-east of the Munch Museum and neighbours the University of Oslo Botanical Gardens.
Tøyen Park is an expanse of grass-covered hills, dotted with clusters of large trees. Like most parks in Oslo, Tøyen Park is a popular recreation area. During summer, groups of people barbecue and fly frisbees, while during winter, tobogganing down the hills is popular. Tøyen Park attracts birdwatchers, where frequently seen birds include the hawfinch. Since 2014, the annual music festival Øyafestivalen has been held here every summer.
Tøyenbadet contains indoor and outdoor swimming pools. The water park features a swimming hall and several open-air pools along with a waterslide and sauna. There is an indoor climbing wall. Small children have their own pool. The outdoor pool is open year-round. The park provides a dressing area and shower facilities
