Tuska Open Air Metal Festival, commonly shortened to Tuska (Finnish: pain, agony), is a Finnish heavy metal festival taking place annually in Helsinki. The first Tuska took place in 1998 and the festival has since grown larger every year. The location of the festival has been in Kaisaniemi park in the middle of the city from 2001. However, since 2011, Tuska has taken place at the Suvilahti event field in the Kalasatama neighbourhood of the Sörnäinen district. The festival dates have always been in either June or July.

In recent years the attendance has grown and the festival has drawn up to 63,000 people in 2023. In 2006, the festival was almost sold out and over a combined three-day total of 33,000 attendees arrived to watch 32 artists, including for example Anathema, Celtic Frost, Opeth, Sodom, Venom, and Finland's own Amorphis and Sonata Arctica.

In 2024 there were four stages named Karhu Main Stage, Radio City Stage, Open Air Stage II and KVLT Stage.
