Metsä (Forest) is the first officially released demo cassette by finnish folk metal band Moonsorrow in 1997. Originally 215 copies of the demo were released , all of which were sold out.

In 2001 the demo got remastered by Marko Tarvonen and was provided as a download. However, the download was later removed from the website. In 2002 the remastered demo was re-released with the addition of bass guitars, keyboards and vocals. At the same time the demo cover was changed.

A completely re-recorded version of the songs "Hvergelmir" and "Elivagar (Pakanavedet)" was released on the EP Tulimyrsky in 2008.

The two tracks Hvergelmir and Elivagar were combined into one track on both the original and the re-released demo.
