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,[1][2] all of which were sold out.

In 2001, Marko Tarvonen remastered the demo and it was then provided as a download.

In 2002, the remastered demo was re-released with the addition of bass guitars, keyboards and vocals.

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