Hemma Beast is a rock band and collective from Helsinki, Finland. The group was formed in 1997 and it has performed at many local venues, most recently at On The Rocks club in Helsinki since 2013. For many years the band performed regularly, usually once a month, nowadays less often due to the members' other commitments.

The setlist varies from show to show and features much improvisation and humorous covers of well-known songs. One standard is a 20-minute long medley comprising of over 100 songs.

Following the death of Zarkus Poussa, the band decided to quit, and performed their last gigs on 15 May 2016 with various guest drummers. In September 2016, the surviving members reunited under the name Borta Beast with a new drummer. The band has been using the original name as of 2023.
